Poor service, poor communication skills!!!

I ordered a half and half triple decker from Debonairs Pizza Sam Ntuli Mall at 17:39 today via the app. I called them after an hour to find out what’s happening with my order than the lady took my number and said she’ll call me back. I later got called by the delivery guy at 18:49 to ask me my address. It’s exactly three hours later since I made my order as I’m writing this review. I’ve been trying to call but there’s no answer. I can’t understand how they close shop while people haven’t received their orders, 3 hours is really too much!!!
