Mr delivery refusal to compensate their customers.

Mr delivery advertised a happy hour special of two for one on your order at selected restaurant's among which was Haveli. The happy hour special ran from 4pm to 6pm our order arrived without a two for one special as advertised after which we showed the driver as well as spesking to their support team while the driver was here. We then spent a huge amount of time on the phone with their support team to resolve the situation by either a refund or to deliver the remaining balance of the 2 for one food. However after countless hours of contact with Mr delivery they are refusing to do either and seem to think that an apology is good enough to make up for their false advertising which is against the law. Through contact with them they had made it perfectly that they have no respect for their customers and that they refuse to resolve the matter. This is not the first time mr delivery had made a mess of our orders. They refuse to take accountability for their mistake and refuse to compensate their customer. We are extremely unhappy with the service and the customer support. I am not happy with any of the service and the legal boundaries they crossed.
