J2efax Charged my bank account San Francisco California

Charge came in 2 days before christmas for 43.90. Call and was immediatley asked for the amount charged and my credit card number. I refused to give my card number then was asked to fax a bank statement with the charge... i refused. The person did not once ask for my name or any information that would allow them to find me in their system... straight to my bank information is what they wanted. On top of that the call sounded like he was driving or outside somewhere. Lots of noise and wind. So he told me to email creditdepartment@j2.com. im still waiting...
