Dissatisfied in the service i received from Mr Delivery

I am so upset with the services i have received from Mr delivery lately. Firstly my orders are not full some items missing, secondly they always late with my orders and thirdly, today i requested a meal for my family for lunch. Once again i trusted Mr delivery and they canceled my order to be delivered, what ****ed me off was the fact that they didn't notify me to say my order ia running late and thwn they just canceled my order and yet my family ia hungry and waiting on the meal i ordered. Perthetic! Poor service! Veey disappointed in Mr Delivery. I don't think i will ever use thier services again!
