You can't blame CCBill for something they have no control over... Vi$a is a fucked up company that loves to fuck with adult webmasters... I am sure it is Vi$a that is holding things up and not CCBill....
If they are not taking your calls anymore there is probally a good reason for that... like they are very busy helping other customers that are not calling on a daily basis whining like a little bitch.
Relax, smoke a joint... it will come through.
