No regard for customers at all

I am utterly disgusted with these people's service, on 22/12/2018 my husband ordered a pizza via the mobile app and it was never delivered. He tried to engage with them via the app, no joy. The restaurant in question (Maponya Mall) never answers their phone. We complained on twitter and only got a response, on the 27th case 549363 was opened. That was the end of it, We still had neither the pizza nor the refund. Started phoning their customer service and they would always promise to get someone to give us a call which never happened and eventually on 12th January they contacted us to ask if we still want the pizza (seriously?) or if we wanted a refund and we opted to collect our refund at a store and that was it. No apology or something small to say we are sorry for the inconvenience, they literally just gave us R130 and when we asked the manager at the store he said he was only told to give us the money and nothing else when we actually incurred data costs, call charges and transport costs to get to this point and debonairs has nothing to say about this. Truly one of the worst experiences ever, no regard for customers whatsoever.
