Poor service to no service

Telkom has installed a wireless network at my residence, and since this installation their has been problems with receiving the correct download speed for which I am paying for. I logged a fault with concern to the download speed that I was receiving. a fault no registered and it was stated that it would be rectified within 24 to 36 hrs. I phoned again after that time frame and still no result. the fault was apparently exculated. I also asked to speak to a manager , where he stated that he will also exculpate it and I am welcome to contact him on the next day. of course I did this the next day, on which when speaking to me he stated that I must in the future not ask for him directly as this makes him look bad, he also stated I must wait until they build a tower in my area for better service, he also stated that if I am not satisfied with the service I must cancel my service at Telkom not understanding I signed a 3year contract with Telkom. This manger has no s****s in understanding the frustration I have for paying for a service that I am not receiving. the manager stated that I cannot keep on exculating the problem and showing my frustration towards the call center. Telkom spends vast amounts of money on adverts*****t to get people to by their product and this client service manager just states if I am unhappy I must cancel contract. I personally do not what to do further as their is no resolution from Telkom side. The review above was the previous one and still up to date nothing has happend. there is no communication between their so back office(technicians and the call centre. Fault outstanding since 2020-01-02. so welcome to poor service from yet another company.
