Can I edit my domain name?

[dvdsmart4]

Hi everyone. I bought a domain name from goDaddy and hosted it with them. I did not notice that I mistakenly typed the domain name as "wwwwmydomain.com", which ought to be " www.mydomain.com" (NOTE: I use "my domain" here just to explain the error I made with the actual used name). So it was at the point of publishing this website that I discovered the mistake, and this was because I got a "pop-up" message saying: 'we hit a snag publishing your website'. Although I was not told by goDaddy that my chosen domain occasioned this snag but this prompted me to check and find out the error I made while entering my domain during registration. Please I want to know if there is a solution to the whole mess up. Can they fix the problem for me? What's your advice ?
