Hi SajhaFan,
I am surprised to see your charge. I hope you would figure out soon. I am not sure how much they would charge for us when we will be moving. My roomates when they got drunked, one of them vomited on the carpet  N another roomate used bleach over it.. the carpet is faded with big white strips. another roomate got drunked one day and broke the wooden wall and there is a big hole in it... We r planning to move 2 months after, i guess we all r F***ed up... lol...
