Unhappy customer😡

I go to BK parkdene branch around 18:11:53 to order order 2 whopper deal for R145, 2 bk crunch for R110, all along the guy assisted us confirmed that my order is all in the bag, I trust all is in order that is why I didn't check, unfortunately when I arrive home the bag my order is in complete and the burger inside is only 3 which is 1 whopper and 2 crunch. I tried to log a complain in their site but just keep on ringing and my airtime is used up.. I can say they are not really doing their job properly while there is not too much people when I do my ordering.. So frustrating😡😡😡
