I apologize for any confusion there may be with the charges on your account! Have you recently uploaded a large amount of contacts, or upgrading your account to our Email Plus plan? Customers are billed based on the amount of contacts in your account and the plan you are under. Taking a look at your account, I can see you were able to get in contact with our Billing Support about this pricing. For your account security, if you have any further questions please give a call back to this Department.
