Precisely. I get that a large portion of the population just wants to pick up the phone and call but that can be totally avoided with so many messaging outlets today.

On the one extreme you can offer voice based support - Just blurt out your question to the phone, system does speech -> text and answers your question. Super super hard.

Interim at least you can offer support on Whatsapp/Facebook where someone can actually ask a question and get answered - a much better version of the chat bots that exist today.
