I had much the same problem, ordered from my favorite local Mexican place for delivery, but Doordash apparently had no agreement with the restaurant, despite holding themselves out as the restaurant. Instead, they posted a menu with incorrect items, incorrect prices and just sent someone to stand in line to order from them.

Needless to say, the food was incorrectly ordered, an hour late and cold. To top it all off, they attempted to charge me for the difference in price. Luckily, I put a stop to this via my credit card, and have boycotted Doordash since.

Unfortunately, this is not uncommon amongst the various food delivery companies, despite being obvious fraud.
