After working with GoDaddy for years and spending lots of money with them, they insisted on making mine and my clients' life miserable during the open EV process. I've even used them for SSL certs before - a few times! I've been trying to get them to issue a certificate for over a month, and they continually come back with new, different requirements. It's like jumping through hoops. Except they're on fire. Or made of plasma. Anyway, my client has lost patience and I lost patience a long time ago.
The staff is usually not rude (though sometimes they are) and they are genuinely unhelpful. It's not that they're incompetent - it's that their system is garbage, and the staff can't give you a good answer because of the way the system was designed. This isn't rocket science. Just tell me what I need and I'll take care of it.
Anyway, trying out DigiCert today. I wholeheartedly do NOT recommend GoDaddy. As great as their support service is for other things, for this, they are useless.
