As a one time door dash driver, this seems credible. Everytime I needed support, even under stressful circumstances, help was available with speed, ease, and solutions.
That said, driving for Doordash is/was closer to a taking out a loan on my car and time than a job/business.
That's hard to believe - I posted my experience above, but CS there seems to be very heavily automated and frequently an actual chatbot. Getting to CS requires going through a number of UI screens. If they are employing an Amazon-level of CS people, then they're horribly utilized.
There is another side of support that regular users won't interact with, the B2B side of things. Might be that those customers take up more time and CS is oriented towards that side.
