Pathethic service

I was checking Mr D and i put a promo code went back to review i did not click on checkout. I saw that the order was showing processing then i looked and it showed in Red CANCELLED. I took a screenshot of this . after a few minutes i get a sms from my bank with transaction for 240 on Mr D. when i looked on the app the order was now showing accepted and processing. I subsequently contacted Mr D the agent advised a customer cannot cancel an order the resturant may of cancelled then accepted. The agent contacted the restuarant and they advised her the driver slready had the order so they cant cancel. I then contacted the restutant the lady advised me the drivet is in front of her and come for pick up. i advised her not to send as i will not accept and i want a refund She advised to take it uo wirh mr d. i contacted mr D again when driver arrived i spoke to a lady i told her issue. she gave an email for me to send screenshot and she will escalate. meanwhile the driver advised he cannot not deliver the order. and i was not going to accept then that would mean me taking an otder which was cancelled i just wanted my refund. The driver contacted Mr D head office on whats app and asked me to write my issue on his phone. which i did . The driver then showed me the feedback on his phone. saying the customer is trying to pull a fast one and that i ordered and now want to cancel. The driver was then called and he tolded me he was asked to take back the order to the resturant. The restuarant never get the order back. I am not out of pocket for 240 the food was returned and i did not get my refund. All i get from mr d is emails asking me for my contact number to resolve the issue. No one calls and then i receive anothet email from Mr D to rate their service.? Who is pulling a fast one now??
