Never to purchase from KFC again!

Sunday last week I purchased 15-piece bucket & paid with debit card. Got bank sms stating sale went through. Teller says it didn’t go through so I show her my sms received. She calls manager who also see sms but says “no it didn’t go through”. I then open my banking app & show them it has gone off my bank acc but they still say no! I then had to pay again - this time with cash so I don’t go through the same ordeal again. I contacted KFC head office to complain & sent all the detail (sms, pic of bank app & slip showing I paid again with cash). I get contacted only to be told I need to take all that I just sent them back to the store I purchased it from, so they can credit me……. I explain to head office consultant “why should I have to waste my time & petrol money driving 30 minutes back to the store to resolve this when I showed them all this “proof” right then & there when I purchased?” Consultant “there is nothing else they can do!” I was so angry at this stage that I put town the phone…….. never, never will I ever purchase anything from KFC again if this is what they think good customer service is! Get your service level up guys… this is shocking!
