drive thru card machineissue and bad service

I went to kfc belhar in my 30 minutes lunch and stood in the drive thru for 12minutes only to get there and be told sorry the card machine is out of order I need to come in. I call the manager on duty she then insists that the notice is on the order boards outside and I said I was thinking what to order and looked at the boards There is nothing. I then had to go into the store to swipe and my order was not ready. I went outside and took photos of the order boards and the notice was only at the drive thru window. How inconvenient and stupid I want to show Belhar area manager these pictures and the service was pathetic. I waited 15-20min inside for my order. I still have both slips from kfc. I want a area manager to call me and I want to be refunded and when I got back to work I ordered a mini sweet chilli twister and it was a normal twister and the chicken tasted burnt I threw that and my hot chips away as it was over cooked too. I will never go there again. Worst experience ever.when Jonathan assisting management was there they never had such issues.
