Hello,<br> <br> On the 1st of August I we to buy groceries at Bara City and ask for cash back as I normally do, 1st transaction declined and I got slip as proof of declined and 2nd transaction was successful, but both transaction went off my account. I went to report a matter a 5days later to the manager with a bank statement she promised to report a matter at Pick n Pay Head office they will reverse the money till today nothing has reflected in my Account and they don't answer their phones at Bara City.<br> <br> I don't have time to go there to check how far she is with my case.<br> <br> Kind Regards<br> Maki
