Terrible service

I had disgusting service from both stores at the Clearwater mall. I was up for an upgrade, firstly the person serving me had NO CLUE what she was doing, it took 2 hours and I was then told they didn't have a nanosim for my new phone but my contract was upgraded. Next day my service was suspended and when i went back the same person was not sure what the problem was. Eventually i found out with no help from them that she set my limit to R5. A few days later returned to same shop for nanosim, they still did not have one, and suggested i go to the iSTORE. I went to the other branch within the mall who acted like they were doing me a favour. They did not want to assist to put the sim in my phone or show me how it worked. The shop closes at 21h00, I was there at 20h00 but they were already entertaining their family in the shop getting ready for home time clearly, to the point that they could not answer any of my questions on the phone. I eventually left to figure things out myself. The service is disgusting, although i have upgraded onto a new contract I am still considering changing to a different provider.
