Prime Letting - More than bad Attitude

A year ago our complex, Summer Place changed admin from Urban Network to Prime Letting. We have been staying there for more than 3 years without incident. Within the first month they welded the pedestrian gates without notifying us. My son and his cousins were at home and only had a key for the pedestrian gate. It caused a lot of issues. When I complaint they said if I don't like it I should move. Eventually they opened the gate. In Feb we paid our rent late, on the 8th of March I already received a letter from the attorneys notifying me than we should pay within 20 days. I know it is our responsibility and accept that, but can you not make arrangements between yourselves and Prime Letting. We paid +/- R800.00 in letter fees and penalties. They blocked our electricity account and even when we paid it, it was an issue to unblock. Today they say they have send letters to ask us to leave our remotes to be reset. If the remotes are not there this morning at 8h00, we will pay the call out. I did not receive a letter. My son is at school with a remote, I am at work, so how do I get the remotes there by 8h00. To me they are unreasonable and quick to say if you don't like it then move...
