Bad service and incorrect billing.

I am really disappointed with telkom's services Sending me a SMS the amount is not R3000 and something. I refuse to pay for services that were not rendered to me. I told them I want to cancel the SIM card seeing the contract term is over. The sales people did not explain what the process is to cancel. I had no communication from them how much I must pay via SMS from March 2025. When I phoned to cancel I was on hold for over an hour. Everytime I phoned and followed the prompt the agent advised me to phone I was transfered to the cancellation department but put on hold. Both SIM cards are blocked since March but when I spoke to the agent he told me the are still sending data to the SIM cards. That does not make sense because we are unable to connect or use the data so why must I pay. I would not even give Telkom a 1 star it is actually a 0.
