Broll property group, Ferreira house

Extremely disappointed I left the flat 3 months ago, I was staying at Ferreira house flat 403 haven't received my deposit, they are the worst very unprofessional, get empty promises, and told my deposit is sent to finance for authorisation I call every day nothing is being done. I would never recommend anyone to do business with them. They dont respond to emails once you've moved out and when they no longer benefiting from you worst company ever. Please assist need my deposit back ***
