KFC IS *****ING PEOPLE'S MONEY

I placed an order on the KFC app for delivery on Wednesday, the payment went off my account but I did not receive any notification or reference number from KFC. I phoned customer care centre and they said they would log it with their finance department, they took my card details and said they would send me an sms/email with a reference number, I didn't received anything. This is unacceptable. I emailed them and just received a case number CAS-***-M8V5B3. The money has gone out of my account, I phoned my bank and they said that the payment was successful and it is NOT on hold so KFC has definitely received the payment. KFC is supposed to send me a confirmation letter stating that they didn't receive the funds like they say so that I can get my bank to reverse the transaction because it was paid and the bank can see from their side. I have ordered off the app numerous times and I have never had this problem before. The amount paid was R144.60 at 12.43pm on Wednesday and till today I still haven't received feedback or my money. This is theft.
