Money back

I bought an OR salad through Drive Thru on the 20 March 2015. and was assisted by 21 Mokoena. She initially told me that my card had declined the transaction, and I have requested the till slip which has indicated as such cos that is the norm. But surprisingly I was told there is no till slip printout. Surprisingly in all that, I received a notify me through my cell phone that the transaction was processed and went thru. I have then informed them, but the Assistant Manager who was called, introduced herself as Matilda assured me that they will call their head office and cancel the cheque debit transaction since they can't do it in the shop. She indicated that she will do it and I will receive feedback after 3 days, its now after 8days and I am still waiting for my reversal. since I had already paid cash for the salad.... All I wanted or expected is better customer service, to call me as promised and sort this thing out. I find it very annoying that a Manager or Assistant does not keep her word in resolving client queries.
