Transfer of contract - no feedback

I phoned MTN on Friday the 20th of October around 10:00 in the morning to find out why my contract still has not been transferred to my name, which was supposed to happen in June 2017, when the contract was upgraded, all the forms were signed and the transfer fee was paid.

The lady I spoke to kept telling me to go into the store, which I am not willing to do. I requested to speak to a team leader and was informed that the team leader was in a meeting and would phone me back before the end of the day. By 14:00 I still had not received a return phone call from the team leader so I phoned the call center again and requested to speak to the team leader directly. The team leader was also unwilling/unable to assist me with my issue and also kept telling me to go into the store. After a lot of me reiterating that I was not willing to go to the store and the team leader telling me to go to the store, I was finally told to phone the store directly.

I phoned the store, informed the person I spoke to about the issue, he took note and told me that he would phone me back before the end of the day. He did phone me back and informed me that it is a system issue and that he had escalated it to the support team. He said he would phone me back on Monday the 23rd of October to inform me if the problem had been resolved.

I phoned the mega-store at Clearwater mall on Tuesday the 24th of October to follow up on my problem and was told I would be phoned back by a manager before the end of the day. I unfortunately missed that phone call, but did receive a voice message which was silent.

Wednesday the 25th of October I phoned the store again to follow up again, and was told by the store manager that I would be phoned back before close of business. No phone call was received. I checked the website for closing time of the store, which is 19:00, so because it was still 18:40, I phoned the store to follow up. All three of my phone calls were ignored by the employees of the store before closing time.

What am I supposed to do? Who is going to assist me with this matter before the end of this month before the debit order goes off on the 1st of November?
