Rental Lost Keys and Charging Rent

[Cassidy Hagen]

We moved out on August 15th but our argeement was until the 30th so we were willing to pay until then. Unfortunately somehow when moving we lost the keys to our old apartment. When we talked to them on August 28th, we explained that and asked them to just go ahead and charge us to rekey the doors. A couple weeks later we ended up finding a key and asked if they wanted us to bring it in and they said to. We just found out that they changed our move out to September 17th and charged my husband’s account for another month of rent. They never told us they were charging and since we told them before move out we didn’t have the keys, it was unexpected. What can I do?
