Telkom is a cheat

I have been having this big difficulty with Telkom over R800 now they have made it R920. I took up this R99pm sim for data with them. Early this year, before the country went into lockdown I called telkom to let then know I was struggling with internet connections. Following numerous attempts of getting help from them to no avail I resolved to cancelling the contract. Consultants told me I will have to pay an amount of R800 as a cancellation fee to which I disputed, citing that I am not receiving the service I took up the contract for. Consultants told me Telkom will have to send through their technician to come validate my connectivity or lack thereof, they told me I will not have to pay the consultation fee should their technician find that I lack connectivity.They finally didsend through the technician, albeit many many months later from the last communication I had with the consultant. Technician found that I do lack connectivity and told me he is to file report advising telling about the validation and he told me the consultant will call me to close account. Absolutely no consultant ever called me following the visit by the technician instead, they handed over my account to debt collectors called NuDebt.. I explained to NuDebt of the situation and they sent me email advising that they closed my account and sent it back to Telkom. However, another agent from NuDebt called saying account was back to them from Telkom. Nobody has responded to my dispute till date
