Blackhawk Network Holdings Inc. Prepaid Card Complaint

Blackhawk Network Holdings Inc. Prepaid card department,

General purpose card Managing, opening, or closing account Virginia

I have a paypower prepaid card. I loaded more than $3000.00 on the card. Now they hold my money and I can not use my card. I emailed the customer service and was told that they can not locate my account. I called the company and was informed someone will contact me. I never heard back from them. However, they kept charging my account after cancellation ( whatever you name it ). The latest Maintenance Fee was charged on -/-/2015. This company is just a scam. Please help.
