Keep your rotten hosed down cicken for stupid fool

I bought KFC at the drive threw on the 13th August. Paid by credit card it shows on my cell phone that the transaction did go threw the bank. They refused to hand over my food saying that they are not sure if it did go threw or not . I phoned KFC helpline they say they will look into the matter in 24 ours and phone me back. case no 133361-KOC6M8. I LEFT without my food. The transaction did go threw proof bank statement. Now they don't want to give my ,money back. Helpline said they must credit me Branch says no. They can keep their rotten hosed down chicken for the other fools that want to buy KFC
