Hi there! Ill preface with short info that english is not my first language, so there might be some gramatical errors :)) And im sorry that it got a bit long

So, I(20f) got a brand new fridge a year ago from my parents. They gave it to me as a birthday gift two years ago in october (2023) because i was starting college and i needed one (the dorm rooms didnt provide any frigdes for residents). Soon enough the problems started to rise. This fridge either was not working and my food was getting bad quickly or was literally a freezer. My parents knew about it, since i nearly got food poisoning because i was seconds away from eating spoiled lasagne (it grew mold and the cheese got all lumpy after like an hour of being out of the fridge). I nearly ate it because in the first few minutes i didnt see the mold - luckily i did see it in time. Then my mom decided to tell me to actually use it as a freezer since i couldnt use it anymore as a fridge.
It was like this till last month, when other guy from my dorm room offered bigger, acutally working fridge (WITH FREEZER!!) for steal price. Of course i took it (with my roommate, since her fridge was also not working) ASAP. Then new problem came up - where to keep my not working fridge? I kept it in the storage room, but the menager of the dorms told me to get it out in like 2 weeks. I put it out, so maybe someone would like to buy it (no reply) and of course called my parents with jokingly saying if they wouldnt like a beer fridge. They told me to sell it. Nothing more, nothing less.
And after two weeks manager called me in to her office and told me to get the fridge im not using out of the dorms. Then it was put in my boyfriend's (21m) car. This week he and i were coming back home for the Easter break, since we live in one city. We had to get the fridge out of the car, to put there our dirty clothes, computers etc. So we decided to put it to the container for electrotrash. Then, once we came back, my dad asked me about my fridge. So i told him i threw it out and he literally say "oh okay". with no emotions. Just literally took a note of my words. AND NOW TODAY. I was in the kitchen cooking with my mom before 2 PM.
She asked me about this fridge, so i told her that we threw it since nobody wanted to buy it and i had no place to hold it in. She got mad. Started passively-agressively saying that im half brained, stupid, this fridge could be brought home, why did i threw it out and that it had still warranty. Then she was not talking to me, I went out at like 3 PM, and then we met up at home at about 7PM.
I've decided to say sorry once again, and then for over 30 mins i had a lecture from both my mom and my dad about how careless i am, how stupid and immature that was, that i dont respect them or their money, that it was a gift, it had warranty, why did i threw it out etc. etc. My mom told me i act like my aunt, which means i dont respect anybody's money or anybody in general and all i care about is me myself and I. Also, She said that i've strated acting like my boyfriend, because "all i care about is money". To add to that, she started saying that i only respect his parents because they pay for our stuff (like take us to trips etc, maybe happened two or three times in the span of 2 years we are together). My mom also brought up the fact that my boyfriend is actually assertive, and he says if he doenst like something.
I quote my mother "Gifts from us are bad, my cooking is bad, my attitude is bad". Not even one gift from then was seen as bad. not by me nor by my boyfriend. we cherish everything we get and we are at least acting that we are happy, so my parents never know. My mom's cooking was never bad - the only thing my boyfriend did was to say what food he doesnt like (for example lettuce, which he was taking out and giving to me when my mom made meatloaf with lettuce). and about attitude - it's about the fact, that my mom talks a lot. and for some time after we started dating my bf told me that its too much sometimes for him. And now after i was studying for some time i actually agree with him, because it can be too much. I know she just wants to be a good host, but its getting too much.
And now I have to find a way to regain their trust and to say sorry even more, i dont honestly know what im gonna do, but i guess i will call the electrotrash company and i will ask if they still have this container.
Now - few quick informations (I will add more if there will be any more questions):

1) I didnt remember about the warranty - i think it was said like once or twice when it was bought. During the time the frigde wasnt really working or the time i had a new fridge the warranty wasnt brought up even once. 2) did my parents knew about the fact my fridge wasn't working properly? YES. YES THEY DID AND STILL THEY DIDNT SAY OR DO ANYTHING 3) The warranty was for 5 years. I probably heard about the span of it once or twice, just like about the whole warranty. But again, noone bothered to bring it up to my attention once the problems have started. (EDIT) 4) I know im already some kind of "adult" but i know i screw up a lit of things and my parents usually help me or even tell me too much (ykwim, they say the most obvious stuff sometimes just to make sure i know it) 5) yes i said sorry. multiple times. still i have to find a way to do something so they forgive me. 6) the only problem (apparently) my parents have is that I "threw out a personalised gift for me from them without second thought the second it was not useful to me anymore " (but it's also about money) (EDIT)

so, AITAH for throwing out the fridge my parents gave me as a gift? What should I do in this situation, after I apologised profusely a few times and my parents are still mad at me because of this fridge?
