INCORRECT FOOD FROM MR DELIVERY = NO COMMUNICATION REGARDING MY REFUND

I received the wrong order from Mr Delivery. I have sent them a photo of the food received on the in app menu whereby the automated response is that an agent will get back soon. However after a few hours of no communication whatsoever I decided to send another photo and complaint through the app. I came to the conclusion that because it is a Sunday, they are perhaps closed. But then again yesterday, Monday 29 Nov 2021, I still have not received any communication back. I proceeded to look for the complaints site on their webpage and submitted my query stating that I am outraged that I have not been contacted yet as I feel I should be refunded. My order was clearly wrong, as I ordered a DOUBLE WHOPPER from Burger King without garnish, tamato, lettuce, etc. But what I received was a one pattied burger with tamato, lettuce, garnish, etc.

Still today I did not receive ANY communication whatsoever. But they are still more than eager to promote their specials and so on, when they can't even give me back my money for a meal which was worth less than the meal I payed for.
