Bad service and no remorse from KFC delivery team

On Friday 24/05/24 at 12h00 I ordered food online and delivery was due at 12h34. At 13h00 it was my lunch hour, however my food was still not delivered so I went back and worked until 14h00, To my surprise my food was not delivered and there was no communication from KFC, I then called the customer care line and I was informed that my order was canceled due to lack of delivery vehicle. I asked why they waited for me to call and all I got was an apology. I asked for refund or voucher since I didn't have another money to order from another restaurant but I was told that I will have to wait 48-72 hours for the refund so I had no choice but to continue with my 12 hour shift hungry and thanks God I managed. Today it's Monday 27th, I decided to call them again at 13h30 since I haven't heard hear from them yet and the same lady is telling me that my refund will be paid within 7-14 days. I am actually very upset.
