RCS Pick 'n Pay Store Account

I made a payment via the RCS/Pick'nPay selfhelp app in September. On 25 October I noticed that the payment does not reflect on my account. I phoned them to rectify but was told that I have to send a mail toe get help. I send the mail with my bank statement and the Pick'nPay account. On the evening of 27 October I got a mail back informing me that they don't see the payment on my bank statement. On 30 October I rep**** attaching the same bank statement highlighting the amount paid. On 2 November I followed up as I had no reply from them. On 6 November I followed up again and then got a reply addresed to Mr. Armand Poungue Deutchoua about a Makro account. Again I followed up about my own account and no reply. I will not recommend this service.
