Thandi: fix ur errors with my contract now!

So I went to Mall of the South to renew 2 of the contracts I have with them. when I got to the store employee by the name of Gift assisted me and then referred me to get assisted by another colleague named Thandi. I specifically asked for a copy of the agreements I signed and I had asked her more than 5 times that both agreements are to be on the same flexOn2 contract. She took it upon herself to change my 1 contract to FlexOn4 and did not give me a copy of my contract, I have been calling for a week now and they always got excuses, either she is not there or she will call me back. today the 9th of Jan24 I finally got a hold of her, I spoke to her and asked her to rectify the mistake she made, but she cut my call, I called back no answer, she called me back and put me on hold, and then said her system is giving her a problem, it has been 4 hours now and she hasn't called back, I keep calling the store number on *** and no answer, if someone does answer and I ask for Thandi shes out... I want this rectified immediately who is going to pay an additional R500 on a contract I did not ask for? This always happens, even 4 years ago Telkom in Traderoute mall messed up my renewal of the agreement, I want a callback and to resolve the issue right way.
