Worst experience

One of the worst experinces I received from a service provider, My name is Dr SM Vilakazi I contacted telkom asking for fibre to be installed this was sometime in 2020 last year. telkom never delivered on their promise but kept on billing me to date, it now turns out that I am 6 or more months in arrears for services I never received. I have made coutless calls and visits to telkom to get proof of that I don't owe them and to have my name cleared on the credit bureau by them and each time I get a run around spoke to a number of consultants such as Neo, Thabile, Bonisiwe and Nkululeko to name but a few and none could help or even show willingness to help. I need a manager to call me back fix this ASAP .
