I've been using the service for about a year. In that time, I've had the "pleasure" of using their customer support three times. The first two times were awful, but I wasn't concerned over the issues enough to continue their runaround game. In the most recent case, I was fed up. I was extremely professional in every email, and clearly stated the issue with related evidence and included my case reference number of all of them. I provided additional requested information to the first couple of responses, but the requests never stopped. No matter what I gave them, there was always another request to elaborate or clarify. Every email was from a different support agent, and it was obvious that they weren't even reviewing my previous replies.
After continuous back-and-forth with constant attempts to deceive and avoid blame, I deleted my Doordash account. Immediately, I received another response that, for the first time, didn't seem copy-pasted. They "reviewed my account and are willing to process my refund, but can't because my account has been deactivated."
Just disgusting business practice. Keep my money, it's the last you'll get from me.
