How can I change my accommodation at uni?

Hi all, I’ve been at uni for over a month now (first year) and I hate it. My flatmates don’t talk to me (slightly make fun of me), the kitchen is extremely dirty and my things always get used or moved around without my permission. I haven’t made any friends with anyone in my accommodation and it’s really stressing me out - not even one person to have a small conversation with. My accommodation is also really far from campus but it was one of the only ones in my budget (we real broke) so I chose it. It’s 3am and I’m writing this because I was rudely waken up by a girl (I’m in an all guys accommodation) banging on my door yelling my name. I have no idea who she was and I feel really uncomfortable with the fact that my flatmates are talking about me to random people despite knowing nothing about me. I only ever feel comfortable using the kitchen (combined with dining area) when no one is there, which is very rare. They always stay in the living room all day, then host pres at night which means I can basically never use the kitchen unless I want to feel judged. I’ve noticed my frying pan has gone missing once (then returned with dried food on it) and all my kitchen supplies have been randomly moved into one tiny cupboard. I have barely any fridge space despite having TWO fridges (I can only fit butter in) and not to mention the flies I’ve seen from people leaving food out (including open DAIRY) overnight. Oh and there’s always an unflushed toilet with pee on the seat . It’s been a month now, and has only gotten worse, so I was wondering if I’m able to transfer accommodations. I’ve signed the contract for my accommodation but I really really want to change. Even if the living situation stays the same, I want to at least be closer to the campus. Would I have to pay fully for a different accommodation or can I just change to a different hall with the same payment plan? And how would I go about this? Do I need to find someone who can takeover my room? Please help 🙏
