Yeah, not sure if its badly configured AI, or an employee not getting paid enough to care.

I wonder if their staff have a ticket quota system that lacks oversight of whether or not the ticket's support needs were actually addressed before it was closed?

I think there is some rule that you just provide contact details somewhere on your website, though some companies try super hard to hide it.

The problem is sometimes the contact method is 12 layers of FAQ pages and web forms. Trying to reduce load is one thing, actively avoiding resolving issues is another.
