Technicians not attending to my fault

I have logged my fault with Telkom on the 12th of December 2017 already. After many phone calls spanning from 12/12/17 - 23/01/18 I have had no luck. I have already escalated the fault on the 5th of January 2018 and then again on the 17th of January 2018.

Can anyone give me an alternative service provider that can actually do the job?
