Ugh. My last apartment tried to say we caused 2k in damages ABOVE a 1.6k deposit.
Admitably, my dog was very good at finding one particular spot of carpet to muss... so they tried to make me pay for taking the 8+year old carpet out and recarpeting the whole thing. On top of saying that I caused water damage and leaking inside the wall with the shower like 2 feet away...when I had asked them multiple times about the consistently wet wood wall that I knew had been leaking from the neighbor side upstairs. =/
We were all so tired of the crap they kept trying to drag us through that I managed to threaten enough with court for replacing end of life carpet if they didn't just keep the deposit and stop harassing us all. They were hemorrhaging residents from that complex because of roach issues they couldn't resolve.
Searching for legal help is such a hassle. I hope that the threat is enough to get them to either drop off the finished product for you or refund you fully, Animallover
