C/c charged but no goods nor refund (online shopping not delivered)

1. Last year tried online shopping, but I still had to go shopping for items that we not in stock.

2. On one delivery their driver reversed into my wall, but no response from customer care when I contacted them to have it repaired.

3. December 2017: I placed an order but it was not delivered 2 days after booked date. I cancelled the order. My c/c was charged, but even after asking them several times to reverse the charge, nothing has happened and there has been no response to about 7 emails other than the automated "Thank you for contacting Pick n Pay, your email is important to us. Please note that we will respond to your email shortly" - but then no response after that.
