Charged for carpet replacement, carpet was not damaged
I moved out of an apartment and was charged $569.06 to replace the carpet. There was one stain, approximately 12x12 that I agreed was damaged. When I moved out, the Apartment Manager alleged, in writing, that I had a pet. I did not have a pet. I am an 18 year Flight Attendant and literally lived in the apartment 14 days a month for a year. I had rugs on every floor and there was absolutely no other damage to the carpet. I believe that this is a personal grievance as I sent a letter to the apartment office after trying to get a lock changed after five requests, with no response. I carbon copied that letter to the Management Partner in California. I am at a loss for the next step. I did not damage the carpet and the Apartment Manager KNOWS it was not damaged. Please advise.
