Pathetic Service, ****s and make empty promises

I'm utterly disgusted and disappointed in this branch service, not only have they got my order wrong they lie and make empty promises. I ordered a meal for my family via Mr Delivery, as it's convenient and easier as I cannot always go directly as I have a elderly father at home and kids. They delivered my meal, but there was few items missing a large chips and mash and graving which I have proof of receipt to show. I immediately called branch spoke to a lady which she hasn't provided a name, I advised her of what's missing she said they will send the driver back immediately. Keep in mind this was in loadshedding. My elderly father can only eat mash as he has allergy with the coleslaw, hence why I ordered that specifically for him. We waited over 2 hours the lady calls and advises they cannot deliver anymore, does not say or explain why, the meals cold no way of warming it again. She promises they will deliver first thing next am at 8am, it's pass 1 still nothing not a call from them. We had to eat a cold meal it's not fair at all. Its not the first time this has happened, and I'm not gonna leave it at this. Bunch of ****s.
