VERY BAD TELKOM NETWORK CONNECTION

I have been experiencing very bad network service with since I have converted my Vodacom number to Telkom a year or two years ago. I am based in Buccleuh in Sandton in a complex. I can go a whole day or two with no connection. Had to use my sister Wifi which I pay every month plus the data I put on my own cell. I usually recharge 5 GB day + 5GB night or 10 GB day + 10 GB night.

Telkom is really a nightmare. Should I go back to my previous service provider or what?

Many people that I know are complaining the same. Now I want use the night data as they are about to finish, no connection at all. Seriously, this needs to be escalated and be sorted or attended to.
