Very very bad customer service the KFC delivery customer care line 😒😡

I ordered food for R85,80 on the 28th of August 2023 using mt KFC app my card details or linked on my app I received an sms stating my order has been delivered I had no call from the delivery guy only an SMS I went outside to look for him there was no drive I sent him an SMS and I called him he wasn’t answering my calls or even replying my text I called KFC customer service and informed them of what happened they promised me of getting my refund within 7 to 14days the lady that was even assisting me was very rude, that was on the 28th they said they proceeded the refund, fine I waited on the 14th day I called I was to wait for the whole day to end so I did I called again on the 16th day, the audacity for them to tell me they don’t have my bank details they need me to send proof the transaction that was made on that day which must be a bank statement and I will have to wait another 7 to 14 days they will send it through email, till today 21st October I haven’t received any emails or even an SMS from them when I called them on the 18th of October…. I’m so disappointed with the customer service of KFC they are very dishonest cause I’ve been using the KFC for a long time they are supposed to see my details cause they even ask for my number which is liked on the app since I have been given a case number for my refund and for my query, I’m tired of calling them asking them for my money which I worked had for I even asked them why do they at least give me a voucher to use it at KFC since I can see that they are not willing to pay me back my money.
