Disgusting service

I have been paying for 4 months for a 200meg line till now I am still not even getting 100meg. I even bought a new router R1500 just to prove the problem is not with my equipment. After 3 months they tell me Telkom needs to do a switch on the line to enable the 200meg. A month in still not done and complaint closed. I loved a new complaint now they have 10 excuses and refusing to give me a managers number so I can sort this out. They quick to take your money or to cut you off if amount not paid but they are ok for you to pay 4 months for a service you are not receiving
