Should I get a rebate?

I moved into some university accommodation on the 10th Dec. A house I had chosen specifically, i did not sign up to be allotted a random room.
A week after I moved in, I developed a rash. It lasted for 2 months; I went to the doctors, they prescribed me with many things and none of them worked. At times it was unbearable.
Found out a week ago that it was bed bugs. I looked around my mattress and found some old cases of the bugs. Called the college accommodation, they sent pest control in and the man confirmed that the bed bugs had been there for ages, it was an old infestation.

The college have given me somewhere to live in the meantime, but I had to move every single one of my possessions, check them over for bugs, boil all my clothes and move them to the new house by myself. (They had said they would offer me help, but on the day they didn't send anyone although I asked them too). When I got to the new house, the bedding was yellow and stained and had flecks of dirt all over it. I had to go and ASK for them to give me clean bedding. Moving all my stuff took about a day and a half and I am completely and utterly exhausted. I can't move back into my room for a month and am stuck in this **** tiny box room.

Should I get any compensation? I am extremely angry that this has happened, especially in the middle of term when I have had so much to do. I'm thinking of refusing to pay rent for the two months in which I lived in unclean conditions. I am also going to get a doctors note and write down how much I had to spend on antihistamines and prescriptions.

Could I also ask them to give me a rebate for this month when I have to live somewhere I would never have agreed to live if I did not have to and is definitely not worth what I was paying before? I've been very nice to them so far because I find it difficult to be offhand with people, should I register my disatisfaction in an email before mentioning anything about money? Otherwise they make think this whole thing was fine for me and that I only worked out i could get money later and am being greedy? Or should I wait until I am back in the house that I want to live in first, in case they don't let me move back?

Thanks
