I cosigned a lease for my son. After he moved out of the apartment with the appropriate notice the the apartments kept billing us ( through a shell company ) for common electric, pest control and garbage collection. I wrote them several times and even sent copies of my canceled checks from my bank but they continued to bill me then put a negative mark on my credit. The apartments are - - - - - -, OH -. The shell company is - - - - - - - -, OH -. I repeatedly asked for an accounting of my payments and their billing but never got a response. Also there is no way to contact this shell company except through mail as they do not have a phone number published.
