Disgusting customer service!

Placed an order successfully at 5:30 & app said that it would be delivered at 6:30. At 6:45 the order still showed as Food being prepared & hadn't even been collected it yet. I phoned Mr D Food to find out what was going on only to be told that they are offline & unfortunately no deliveries can be made even on orders made earlier. She then proceeded to tell me it's fine she will cancel my order & refund me & then I replace the order & collect it myself!! So at 6:45 in the evening I must pack my young kids in the car & head off to a restuarant to collect food for them! What is the point of Mr DELIVERY?!! The worst part about this whole thing which is the reason why they have lost me as a customer is that it didn't even cross their minds to inform their customers who had placed orders about the problem! The could very easily send out a bulk sms to their customers informing them of the issue instead of letting us sit for over an hour waiting with no update whatsoever. Disgusting customer service!!!
