BAD SERVICE AT THE PARKS!!

So I recently changed units for December and I had paid all necessary costs from deposit and first month rent and admin fees. After I made payment I got billed for the previous unit I was leaving....they deducted rental for it. I made them aware and they said they would do a reversal which didn't happen. Next thing they said they would make 1 payment with my deposit and refund me all my money. Normally it takes up to 14 days for this to be done but till today no communication nothing. I have sent a whole chain of emails to different people asking for assistance with no help. I waited for so long to do the exit inspection but nobody responded to my emails until I got called by an agent who wanted me to do it on a day i wasn't available. he ended up doing it without me there. Now I had to still call yesterday to find out what's going on as we in a new month and yall already even took rent for the new month but hadn't paid my koney back. To my suprise nothing had been processed until now meaning had I not called I would have still not received my money. Now to my suprise I'm being billed R3500 for painting of the walls which doesn't make sense as the walls where clean with no stains or marks or paint peeled off anywhere when I left the unit clean. This is not yhe first time this has happened which to me feels like a **** and trying to rob me off my money. I got bills to pay and you guys want to just hold my money. I swear I'm so close to moving out of this place.
