Landstar properties ****mers

Landstar properties does not pay back deposit.after a year and 3 months living in a flat run by them at Centurion place forest Hill, they are holding my deposit.they have sent me a quote for painting R14000 , which is ridiculous. the one Agent assured me for the refund but she and her office stopped replying to my emails and phone calls.in the time I lived there I have been replacing security gate locks out of my pocket because they don't maintain the building.They asked me to put good word for the new tenant in order to get the deposit and promised to pay me back.these are ****mers if the place was trashed how come the Very next day I moved they had the tenant I convinced move in and pay deposit? am warning the public .
