Attitude and Card Machine

On Wednesday me and my friend, with our 3 babies, went to KFC Gateway. When I paid for my order, the cashier told me it did not go through because of communication error. She the swiped my card again. This time I received the message on my phone, showing that it did go through and the amount was deducted from my account. Howecer, the lady told me it still did not go through. I then wanted to show her the message, but she went to get the manager. The manager did not come back with her, just told her to tell us to pay cash?! Cars are hooting behind ys, our children are crying. I insisted on speakibg to the manager. My friend then paid, again. I was assured that the money would be refunded which it was not. Apart from that, we have had stale buns at the same place on 3 other occasiins. I will not be buying KFC again. No wonder everyone complains about the place
