Student housing

Hi, I was living in a shared flat however my contract ended and the landlord didn't allow me to live any further in fact he forced me to leave so I had to find a new room asap within my budget. I went to see this room and there was a woman and her husband and their one kid around 14 years old. I didn't have time to look for different options so I just confirmed this one within a day. Though I made them aware that I'm a student and I mostly work from home and that I prefer quiet space. They were okay with it and when I asked how many members live there they said it's just them. So I paid them deposit and moved my stuff. But after I have moved my stuff I see there are two couples not one living there and a bunch of kids (around 8 kids age range from 1-18 years) and they are so noisy. Both women were so judgmental that they'd make comments whenever I used to work from home that this girl does nothing maybe that's why she is in her room and not outside. I was working on my dissertation and the reason I wouldn't go outside everyday to study was that I was on low budget so on days it wasn't necessary I'd just work from home. Second they never turn on the heating (it was winters that time back in Feb) if I ever ask they'll make excuses. I prefer to order my groceries but whenever id order something online they'll make comments like why do you order online in a way as if I spend so much money asking where you get your money. If I'm laughing in my room they'll make comments “some people stay in their room laughing whole day”. Even the lady said to me two three times that I have this work to do im baby sitting some kids would you do that I said no and she was like since you are “free” I thought I'd suggest you something. Then another thing is that they'd turn off heating in the kitchen whenever id go to make something (I only meal prep three times a week) and when ill ask they'll be like there's some issue with the stove the landlord never listen to us we also are not able to cook but then ill see them making dishes worth whole family. Their kids would just come to my room and mess things up whenever I was outside and when I start locking my room that lady took it personally and never talked to me. This whole situation wasted three months of my time as I couldn't find another accommodation within my budget. I understand it's not a lot but I was just not able to study fully focused and my dissertation also got capped at 50% as I missed the deadline and my EC was also not accepted. I always paid them rent on time and I kept my room very clean during my time there but I feel like treating a tenant the way they did is just so unfair. I sometimes feel so regretful about this whole situation and feel like making a complaint
