pathetic customer service

Contacted the call centre today spoke Ouma, I told her my 2 queries. First query, no feedback given over a month and no reference number. Ouma said she will investigate and get back to me but did not. 2nd query I was given a rain check, I went there few times during the month there was still no stock. On Friday there was stock, given the rain check was due but was charged for one item normal price. This product I did not take I was charged for something I did not take. Ouma told me she will send message so I can send photo of the till slip on watsapp. As yet no message. I phoned after lunch and left message with Megan for the supervisor to call me. But Megan gets Ouma to call me. I told her I want to speak to her team leader. I was given a call approx 3:15pm. the team leader just goes on talking without allowing me to speak, No customer ethics, need to listen to customer instead of rattling away. Call should be listened to. Service is terrible at the customer care line. The team leader was to get her manager to call me but has not done so.
