Try getting support for anything that's not G Suite or Project Fi (which have arguably good customer support). Sometimes the "support" is just a link to the forums.
"Paid with data" sounds nominally accurate but misleading.
Suppose there were a paid mail service, and another free one with a billion users, and the paid service's spam filtering relied on the free one for accuracy. (Spammers can't very well spam a hundred thousand people without hitting at least a few thousand of the billion.) Would you say that the users of the free one pay with data? They do, but to me, the phrase "paid with data" suggests other data than just the spam you get and whether you click "this is spam" on a particular message.
