Riverstone Residential Group deposits cleaning charge false lies , Internet

Riverstone is an unscrupulous management company, that will go to any lengths to keep your deposit and charge more when you move out.  I was promised by email that if I allowed the maintenance staff to enter my apartment a week before my lease was up, I would have the last week of my paid rent prorated. The maintenance staff did make use of the apartment for painting etc., yet when I moved out I never received a refund for that week. Not, only that they did not return my deposit, for an apartment that was immaculately cleaned, and charged me $200 for a closet door that they claimed was cracked (no crack existed). I contacted the management company, and they claimed that they were not able to rent the apartment as early as they wanted, so they would not give me a proration for it's use, Although, I found out that a new resident moved in a day after my lease was up. So they benefited a weeks worth of rent, by preparing this apartment for my last week that I paid. I asked the management how they treat there customers like this and she replied that it does not matter, because I  am not a resident anymore, and that they would be submitting by bill to collections, and then hung up the phone on me. I called back again and asked for record of the maintenance staff entering my apartment, and she said that I would have to get a subpoena, then hung up.
