Poor Customer Service

I had a contract with Telkom that ended March 2018, beginning of February 2018 I called their call centre for processes to follow when the contract is about to expire and the lady that I spoke to sent me a form to fill in, in order to cancel. I completed the form and sent it back to them and I still have emails as proof that it was sent. They debited in April 2018 after my contract had ended and when I called them, I spoke to a lady by the name of Lungi Ngubane and asked me to re-send my cancellation form and she copied her team leader, still the contract was not cancelled. They debited again in May 2018 and I was very furious of this bad service. I decided to pay them a visit which costed me above R400 of travel costs, there is no Telkom in EShowe so I drove to Richard's Bay to cancel it and only then it was cancelled. Then I had an amount of R2279.86 to pay because they didn't do what they were supposed to do. I don't intent on making any business relationship with Telkom SA ever again because of their poor customer service.
