I have been in contact with the customer care of telkom, and their service agent on their customer care consultants really give out bad experience for clients. I have a contract with telkom, and as soon as they find insufficient funds in my bank account, the charge clients R203.00 per debit order that fails due to unfortunate circumstances. I have a R210.00 Sim only contract with telkom, and currently, my service is suspended, I am expected to pay R799.00. Even if I pay, it never goes down. With their agents saying there is interest added to the account on monthly basis.I want my service back but after I made payment with an agreement that I will get my service in 5 to 24 hours. The service agent told me that I will get my service back in 7 working days. I tell them I to help they advised me to go open a case at the policestaion to get the conversation with the agent that messed up my account. Telkom doesn't deserve a star they don't care of their clients and only care about interest than clients
