I have long held, since prior to the cloud era, that I would not trust my domain or web hosting with a company that wouldn't put a real human on the phone with me. And in the past, I've tested this prior to signing up. For my web host, I called support when I was still evaluating, at 2 AM, and got a guy on the phone named Chris, with a very strong Texas accent. I signed up immediately, and I've been a customer over ten years. (One good human interaction can buy you a lot of brand loyalty.)

This is more difficult today, and some of the providers I use no longer provide phone support over having a ticket system only, but the ability to address issues with the service should be a primary consideration of any company you base your own business on.

If you're looking at signing up with a company that won't take your call, and a competitor exists who will, go with the latter.
