Would you buy from a firm that has a policy about not accepting phone calls

Absolutely, as long as I can communicate I'm Ok with it.  Actually I prefer e-mail, I can think about what I want to say and put it as clearly as possible.  Phone calls are great, but many high end companies are small and don't have the staff (or funds) to have a dedicated person to answer questions on the phone.

I'm an email guy as well.  As a long time auditor, I like an an audit trail in case there is a misunderstanding in the future.

As for he O.P.'s point, hopefully the firm has a rational basis for their decision to lose a certain type of client in return for savings in support.

Actually, if you request by email, Amazon will call you within minutes...I was pleasantly shocked ! Many companies will only take initial communication electronically, but will talk to you afterwards...

No phone calls no sale!!

I we were to gauge friendships based upon returned phone calls, my grandkids would be my worst enemies. They return text messages in a flash, but phone messages? ... not so much.

Taters ...

Time to enter into the new world, lad.  It's all digital now. *lol*
