Bad service

Good day, i am a very unhappy customer i placed an online order with Diepkloof Plaza Debonairs which wasn't delivered. The driver sent me a please call of which returned the call immediately and there was no answer, i tried calling him 2 more times with no answer. I proceeded to track my order which showed that my food was delivered to me on the app which was untrue. My order is number #***8 i have called twice into your call centre and have recieved absolutely no help this is unacceptable. I was transferred to some number where i could hear people talking in the background and no one responding to me
