Bad after sales support

We first moved to paulshof in gauteng in November of 2017 and we decided to take the route of cell c fiber to our house and we were so impressed with the service, the rep came to our house and set everything up in a flash, and we were very happy customers for the first 2 and a half years, the suddenly for some reason the fiber crashed, and it took almost a week for cell c fiber to restore our connection wich is shocking needless to say, but we were happy campers again, the to our surprise in a few short days we started haveing slow internet and unstable connections, so we had since then upgrade our line to a faster more stable line or as we had hoped, but the saga continued with multiple phone calls and been on hold for hours and this issue is still not resolved, if anyone out there is looking for fiber I would suggest you steer far away from cell fiber as it appears to me that there tech support is sadly lacking
