Horrible service , rude manager!

My partner and I ordered pizza online 26 Jan 2020 Sunday .Debonairs pizza Summerstrand accepted the order. I was offered the option to track the order and it stated that they were still preparing the meal. We waited a full 30 mins, it still stated that they were still preparing the meal until moments later a message popped up "sorry for the wait..." . We continued waiting and then notifications started popping up in an interval of 2-3 seconds"delivery is on it's way" , "delivery has arrived" . I was confused because I had not even received a call from the driver but I went outside to go check, there was no sign of the driver. I was offered an option to rate the driver and I rated him one star since I had not received my order. I made another order, meaty triple decker since I had not received the 1st order which was meaty double decker crammed crust . We waited an additional 15 mins. I got a call from the driver and he said he was outside , I went to go fetch it thinking it's the 2nd order but it was actually the first , I complained about the service and told him what had just happened and he said the problem was with the system . My partner then called Debonairs Pizza Summerstrand (041 583) inorder to cancel the 2nd order and tried explaining the situation , instead they found his English amusing they were giggling, he started getting frustrated so I took the phone and I explained the situation in xhosa. The person who answered our call then agreed to cancel the order. A few mins later I get a call from *** , I'm assuming he's the owner, from the moment I answered his call he spoke in a harsh and an impolite manner .he was so disrespectful ! He raised his voice when he was speaking to me and I was shocked. I tried explaining the situation he blamed me instead, he didn't want to acknowledge the problem was on their side, he then dropped the call . I tried processing what had just happened I then tried calling him because I really felt disrespected but he didn't answer . He was rude .
