If they get you on the phone, they can tag you as a mark and upsell you.

If you didn't get the upsell, maybe you "passed" for whatever their heuristics are :^D

That would explain it, indeed...

But that's a pretty dark pattern, isn't it?

Do you happen to have some confirmation that they do it in that intent?

Also, if this is the case, why don't we see more people complaining (here for example)?

Because the victim would not be here (I'm trying to compliment you, here!).
