Very bad service and unapologetic about a legal order

I had place an order for a family of 8 people on the KFC app, for us to collect in store. Paid what I ordered in the basket . My wife had to do the collection as I was unable to drive due to a medical condition. When she got there the order was not placed as the order number did not reach the outlet until today. I called the call centre and the told me they have a technical problem. Told the lady I have family of 8 and that was at 19h00 . I gave her my email address and until today she did not send me an email. My wife had to place another order at the outlet . The call centre lady said that it will take 24hiurs for the refund. How they going to send the refund as I did not gave her my banking details. My wife called them again yesterday as was now pass the weekend. They told her that a refund will take place 7 to 14 days ,which I think it is absurd . As an call order. You expect your food to be ready if you call an hour in advance ,Kfc did not once call or email me for the inconvenience they have caused. I would not have placed this review if they have called and accept their responsibility
