PROBLEMS TO GET MY MONEY BACK FROM FNB

ON THE 1 JANUARY 2016 I purchased food at KfC Alberton i put my card in the Banking Machine and it shows the transaction is approved when I give the machine back to the Lady of KFC she said they went ofline I must put my pin in again the money will automatically reverse back with a sms. I did that but nothing happened only got 2 sms from FNB shown that I paid R118.90 twice to KFC for food. so the call the Manager on duty REFILOE from KFC Alberton and she said if the money was not back the next morning we must come in to her so necxt morning we did go there and se took the card number ans said it was not been paid over so they will let fnb know to reverse it immediately back into our account. on the 2 of January received a sms from FNB the reserved funds us now release we must check the balance so it did look if it was back only to receive a sms from FNB onthe 6 of January that they paid KFC again! We call Fnb private Banker immediately on the 6th he said we must fill in n despute form and they will reverse the money back it was FNB ,s Fault they shoud not paid the money over again! it is today the 14 of January and still they did not pay the money back!!
