Poor, poorer, poorest. Will never in my live recommend Telkom

When I signed a new LTE contract with Telkom I was promised a 10mb speed line. The first two days everything went well but since then the best speed we get is 2mb. I made a promise to pay the contract for 24 months. But Telkom did not keep their promise. Why must the customers pay for something that is not what they expected to get in return.? I was told that I can cancel a contract in October 2018 and that is the reason I signed a new contract but when I went there to cancel the contract I was told that I must still keep the contract for another year. They refuse to told me who the person was who said I can cancel the old contract, but I must pay. Also I was blacklisted for a contract that was cancelled online but was never cancelled. If Telkom personnel can't do their job and can't keep up to their contract term then my next step will be to work through the OMBUDSMAN. Working from home and relying on wifi, Telkom is costing me a lot of time and money. So I suggest that you be in contact with me ASAP and fix my problem or further steps will be taken.
