Hello AmyISP,
Unfortunately we are not able to help you with billing issue here at the forum. I was able to find a phone number for our Customer Care Operation @ Phone: 888-339-7887 billing and invoice support.
I have had a billing issue that I have been trying to get resolved for over 3 months. Repeated emails have resulted in no resolution. I have tried marking "Dispute invoice" online and this has produced no response at all. What is the best method for getting billing issues corrected in a timely manner? This extremely poor customer service is incredibly frustrating.
