Support chat is pretty terrible, but poor quality phone support isn‘t that great either, in my view. (High-quality phone support does exist, but is unfortunately increasingly rare.)

I wish email support was more of a thing in the US. Not chat, not a web-only form or ticketing system, just plain old email (on the frontend):

It leaves a paper trail (persisted within my control), it has minimal overhead (the forced superficial friendliness or attempts of small talk in support chats are deeply disturbing to me), it works on a bad internet connection, it works asynchronously.

In the EU, having a human-attended support email address has recently been made a legal requirement, and I‘ve had great experiences with it (if only because in some companies it seems to immediately get you to a second level support due to the relatively low volume compared to the "official"/advertised means of contact).
