I was automatically rebilled today after never being warned that it was an automatic custom of theirs to charge $20 to your account. They never once tell you that auto-renewal is on and they conveniently don't e-mail you about your domain expiring (which is obviously an important e-mail to receive and all other places DO THIS!) and charge you. They refused to refund it even though it was still waiting in authorization and could have easily been reversed.
These people are the rudest, sneakiest jerks. Not only that the service is sub-par, terribly priced, and they'll send you spam in the form of snail mail and call you.

Do not use Godaddy!
