WRONG INFORMATION-BAD CUSTOMER SERVICE

I went to the Store on the 2nd November to do a Sim Swap, the guy called Thabiso made me pay R136 and asked me to switch off my phone for 24 hrs. When I try and switch it on, it still says my sim is not registered with the Network. I called customer service and they advised me that the sim swap was never done and when you do your sim swap, the phone should always be on.<br> My problem is that im now trying to call the shop for them to rectify this mess because im not willing to drive to Westgate mall, but nobody is picking up the phone
