Worst ever service from Telkom!

An agent from Telkom contacted me in Nov'20 to sell a unlimited data contract which I accepted. A few days later another agent from Telkom contacted me to inform me that the wrong product was sold to me, it is a business unlimited data contract that applies only during office hours. I asked her to cancel it as I am at work during this time and will have no need for the data at home during these hours. I do have a 10GB data contract at Telkom since 2019. According to my understanding the business contract subscription was cancelled. In February I noticed on my invoice that I am billed for the Business unlimited contract. I refused to pay for it as I did not accept this contract or used any of the data, it was never activated from my side. I reversed the debit order and made an eft payment for my 10GB data contract. The next month i was billed for the Business unlimited contract again and a penalty fee of R2020 was added to my account for not paying it the previous month. This is now going on since Feb'21 and I have made several calls to the Telkom call centre and I went to my nearest Telkom shop where they did a formal dispute for wrong product sold to client and wrongly billed. So far I had no luck in sorting this out. I have been paying via eft my 10GB data subscription every month, but I refuse to pay for the other contract as I did not accept it. Two weeks ago I received an email from Nudebt on behalf of Telkom where they inform me that my account has been handed over. I am furious as I never missed a payment in my life and will now get a bad credit rating and eventually a summons for Telkom's stupidity. I just received my new statement and the Business unlimited subscription amount and penalty fee is still reflecting on my account. Telkom has suspended my account due to this and therefore I am not able to use my 10GB data contract which I am paying for every month. I don't know what else to do as Telkom call centre agents is *********** and the Telkom shop agent can't assist me any further, Nudebt don't know how to sort this out so can someone from Telkom who knows what to do please call me and sort this out. I will be cancelling my 10GB data contract with Telkom also as I will NEVER make use of Telkom again. The worst company and service I ever dealt with in my life!
