TELKOM TERRIBLE SERVICE

I have a telkom LTE 10 meg line whereby i receive line speeds below 1 meg. I have logged a complaint on the 08/09/2020 with initial reference number(***9) since then the reference has changed 3 times and now the latest reference is number is ***9. Telkom sent a technician(James Madhlala) out to assist on 10/11/2020 but the technician failed to solve the issue. Telkom has since been using delay tactics and threatened me that if I cancel the contract I will have to pay cancellation and penalty fees. In my last communication which was today(19/01/2021) the call center now says that the technician did not update feedback to telkom and that is the reason that they cant do anything till they receive feedback from technician, I been trying to contact the telkom technician, he just doesn't answer and he reads my whatsapp messages and does not respond to them. This is a terrible service received from telkom!!!!
