The customer care phone number is: 1-207-623-6309.
They are open from 9 a.m. to 2 a.m. Eastern time. (Note that's 9 a.m. to 2 a.m., rather than 2 p.m. In other words, they're open practically all day and night.)
You can also reach them by sending email to: help@virginconnect.com
Finally, I may as well include their snail mail customer care address too (dunno why, really, but here it is anyway):
Virginconnect
P.O. Box 241
Brunswick, ME 04011-2013
I hope this helps you.
