Disgusting Telkom

I am truly appalled by Telkom service at the Maponya store. Last year November 2017, my mother and I did change of ownership of the contract. We changed from her name to my name and we were told the change of ownership has been done . December they will not debit, I need to pay directly and they will only start to debit as of January 2018. I waited for the debit order to go off until today no debit order has gone off. Now the account is overdue and change of ownership has not been done and now my mum is going to be handed over to the debt collectors. I need this matter to be resolved promptly. It is not my fault or my mother's fault that the account is overdue. Telkom is liable for this issue. Someone needs to take responsibility.
