Complaint

Hi Admin, can I be assisted,, here goes my story.

Last week on the 23rd of October, I went to Boxer Superstores in Cleary Park Port Elizabeth, I bought groceries and asked for a R1000 cash Back, when I arrived at home I noticed that the cashier double deducted the amount from my account, I tried calling the store without a success. The following day I went there and I was told to bring the bank statement, of which I did. The manager there said he'll escalate the matter to the IT Department and call back, but he did not. We've been calling them and the only response we get is that they'll get back to us in a few and never do that. So I called again on Thursday the 29th, I asked the status of the claim, I asked the manager to give me the Ref number of the claim, asked him to cc me on the email he's sending to show that he's doing follow up, he said he doesn't have an authority to do any of that and doesn't have an authority to refund me. I don't know what else I can do now, I want my money back. Please help
