Mr Delivery .... Didn't Deliver!

Last night I experienced incredibly bad service from Mr Delivery. I ordered just over R300-00 worth of food for my wife and I as a Birthday celebration. The order was placed and accepted using the Mr D mobile app at 19:12. The app informed me that the food would be ready by 19:52 and the expected delivery time was 20:07. By 20:00 I had heard nothing more from them and tried to phone, which proved impossible as every number I could locate for them was an automated message telling me how to query using their app or website. I lodged a complaint on the app at 20:25 once it was clear that the delivery was now overdue. The app was still stating that the order had been accepted. I then phoned the actual restaurant who informed me that they had already closed and were waiting for Mr D to collect my order, which had been ready and waiting for collection for the past 45 minutes. They had spoken to Mr D twice during this time and they were advised that a driver was on his way. At 20:4 (approximately 90 minutes after the order had been placed) I received a call from Mr D in response to my query on the app to inform me that the order had been cancelled and they would be refunding my payment either as a credit to the Mr D app or to my Bank Account. I naturally chose my Bank Account. No explanation was given as to what went wrong. What a disappointment! I guess the peanut butter toast I ended up having wasn't too bad for a birthday dinner ... To add insult to injury I received an email a short while later informing me that the refund would be processed in approximately 5 business days. I would have thought in a case like this that they could do an immediate payment. This was not my fault at all. I will NOT be using the services of Mr Delivery again.
