Mr D Food app - dismal service

I placed an order on the Mr D Food app at 16h53 and got confirmation that the food would be delivered at 17h29. The food only arrived at 18h20 because the initial driver had car troubles. In that time, Mr D did not even bother to inform me about the delay and the onus rested on me to gather information. To make matters worse, the drink was lukewarm and the only compensation I received was only 30% of the entire bill. So, basically Mr D is saying that the entire experience of inconvenience, calls I made to follow-up, delay, and bad food is only 30% of their responsibility and 70% mine. Uber Eats has a better customer policy and resolution strategy. This is unacceptable from Mr D
