Customer Contempt at it's finest

The delivery service here is the worst I've had to deal with from all the Supermarket delivery services. I've literally had to call in on 3 of my last 4 orders which are always running more than 30 min late. I'm done using this delivery app and unless you plan on frustrating yourself you should be too. They literally could not care less and it's abysmal how they treat customers as if their time doesn't matter. Wish I could start a boycott.
