I ordered a box with unitedcolo but changed my mind 45 minutes later. I sent them an email. Do you think my cc will be charged?

:(

call them. their number is on their site. the signup may be automatic and they may not get to their email right away.

the signup is not automatic. They will get back to you. On the other hand, why do you sign up and change your mind 45 mins later... I don't think much can change drastically in that short time frame that makes you change your decision

I dont think they charge your CC untill the server has been setup. So you should be safe.
