Nandos - *******

I ordered Nandos food on the 14th September@10:17 at Greenstone Mall. I paid with my debit card the amount of R103. Then was informed by the operator Llwandisa that the money did not go through even though i showed on my phone that it did indeed. I then had to pay in cash for the food in order to settle the meal and was informed that Nandos will credit me the amount i paid on my card. On Monday 17th September i went back to Greenstone Nandos to follow up on the credit that did not take place. I was informed to draw a statement which they will need to refund me. Each time costing me 20km of fuel and my personal time to resolve the matter. I returned to the shop and the statement was presented to the Manager of the shop. He confirmed that the money was reflecting in their bank account as was on my statement and that no refund was made. I was informed to request a request with my bank that the transaction was indeed a legitimate transaction, which it is else i would not have appeared on my both my account and Nando's account. I am not happy at all with the service and response received from the shop
