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


Personally I would not. Call me old school but to me communications are the most important thing in handling business situations. Sure e-mail, faxing and texting are all great but nothing makes up for personal service you receive from getting a phone call.

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...
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.

Time to enter into the new world, lad.  It's all digital now. *lol* 
And that is what is wrong with our society. It's become so in personal. We wonder why we don't know our neighbors anymore.
