Bad service with Vumatel

I have limited to no internet service. I have contact Telkom which helped me through several proceedings to solve the problem,(that took about 2 days & 4hours on a cellphone) but with no luck. A fault was logged with ref. nr. given. when phoning back to check progress on fault, it was stated "closed" problem solved, which was not the case. My contact nr. was given to a Vumatel technician twice and I was never contacted and the problem is still not solved. I work from home and the reason I got Fiber was for better internet. I cannot sit on my phone for 2 hours every day trying to solve this problem. And every time I phone to complain the Telkom consultant has to go through al procedures before they can log a fault and the Vumatel technician never call to see whether the problem is solved. Very bad service and I pay for services I don't get I don't know how to solve this ADSL was much better
