I move out of their premises since last year October but still sending me the Bills they put me out before even my contract got expired because they got better offers but still sending me bills I send them emails to ask them to remove me into their system but they don't want to respond last month I had a bill more then 40.000 and I know ***** they are they can one day claim that money when they know that I'm was out and they were giving me my deposit bit by bit while they took mine in fool and I don't own anything...
