Poor, *********** and slow customer service

I went into a Telkom shop on Saturday 23 June wanting to have my LTE Smartbroadband wireless converted to Prepaid Smartbroadband wireless so I could better manage my data. The assistant in the shop told me they could not do that in the shop, I must first cancel the service online. I did this and added a comment that I wanted the number on Prepaid. On Friday 30 June, instead of making the LTE service prepaid, Telkom simply deleted my wife's FreeMe mobile number from my account. Her phone has not been able to make or receive calls or SMSes since. I complained at the Telkom shop immediately and the assistant logged a fault (ref ********** 0, ********** 9). It has now been nearly a week and nothing has been done. This is both a safety and security issue as several accounts are tied to that number. Please fix the situation ASAP.
