PEP store Manager lack of customer care service

It was about 16h45 when I get inside PEP store at Phangami Mall to buy new starter pack. But unfortunately, things did not work out well even if Rica was done in-store. I failed to register it on the Network. The following morning i went back to explain the problem but was ready to buy another new starter pack. There was another women called herself a manager said who denied to sell me a starter pack because I was refusing to buy another R10 airtime for the new starter pack. I explained that yesterday when I bought that new starter, I was forced to buy R10 airtime which I did not use it, because the SIM card did not go through and I was so disappointed by her behaviour towards the customer. I think you better take her for training in customer care service because she is not friendly at all. When I asked to speak to speak to someone except her she said she was the only store manager. Thank you.
