Spar please reverse my money.

I went to Spar Mall@55 on the 8 July 2018 at 17:26. I purchased item worth R174.13 and requested a cash back of R350,00. The transaction declined on their side but on my side a notifaction came in and the money went out of my account. I immediately spoke to Tlalane who gave me attitude and telling me that the money will be reversed within 24hrs. On monday the 9 July 2018 i went to the store and spoke to Veronica who asked for my bank statement and assured me that the money will be reversed. The money has not been reversed, i called my bank (FNB) they gave me the authorization number that Spar can you to release the money back to my account, i gave the authorization number to Veronica. On tuesday i called the mamager Christo Fourie telling him my problem but he didn’t entertain me instead he told me that the money is not with them i must go back to the bank for them to give me my money. On thursday Veronica told me that the money shows it has been reversed where as she told Clenda(Customer Care Consultant) that they have lodged a query with Blue Label for them to trace it.

Kindly assist as it has been 7 days now and i haven’t received my money. To make the matter worse they have took they purchases funds doe the items i bought which resulted my banck account to be on excess.

I asked my self that if it was someone else were they gonna treat him/her the way they doing to me or the process will be this long.

Spar is failing me as a customer and what i want is for them to give me back my money. Im tired of calling them n doing up and downs.
