i had the same problem as my plan was scheduled for renewal yesterday..i think due to site was down it did not process charges...but then this morning it finally went through and all was fine except, that the plan did not update to the new promo..which is only a minor problem as my line works....
so check your account status ... i would not recommend to use"pay now" if you were set up for auto renewal as system might process your auto renewal soon and you will get charged twice....
cheers
