It does not sound like you are in America, so I would say no. You might be better either just emailing them, or talking to one of their on-site people. I believe they have one of those live agent blocks on their website.
I dont know but the websiute www.saynoto0870.com may be a help, it will give a freephone variation, if there is one.
What do you mean by free? The support from godaddy is free. The phone call may cost money depending on how you call them.
Did you call from an airport payphone using a credit card or something? I just tried the number as an experiment and was billed €0.01 for a 1-minute call.
