Pathetic every time..

I don't know why I keep using the mr. D app because it is always a horrible experience. Nine times out of ten they send the wrong food, or the restaurant just cancels your prder an half our after you ordered. This happened again a gew days ago and I'm still waiting for a refund. I'm quite sure they've done this before as well because I dont always check to see if the refund was paid. What a pathetic little business. Please don't support.
