GMA management is the worst

GMA took over our complex in Kempton Park this year and it’s been downhill from there. As owners we pay the maintenance and up keeping of our complex yet we pay them levies every month. I own a 1 bedroom apartment and my levies are R4000??? They don’t answer to emails or phone calls. Their staff members are very dismissive and rude. We didn’t vote this agency in and now we are stuck with them.
