Mr Delivery third awful "delivery"

Placed an order with Mr D and I recieved a notification that their driver had arrived at the restaurant at 19:21. The driver proceeded to stand there and not move for the next half hour. I called the call centre where an agent told me they will look into it and no one ever came back to me. I called again the driver had now not moved for 45 minutes and I asked what was going on. The call centre saw on their system that an enquiry was made and they were unclear whether they had reached the driver or not. They then offered to cancel the order and refund me so I could place another order immediately. I got a cancellation notice but KP refund. When I called back a third call centre agent informed me that it could take anywhere from 24 hours to five days to be refunded. This is my third awful experience with Mr Delivery. I've previously had drunk belligerent drivers arriving over an hour late with a call full of people and loud music and other incredibly ride drivers
