Charges come up on my card, I had no ideal what they for on the March bill. There are charges that I charged to (STAMP.com ) on the April billing. But there are none that I made on the March bill. No one has access to this computer or the charge card. If there is a mistake on my part, send a mailed bill and I will pay it. I want a refund and for the charges to stop. I'm willing to never do business with this company ever again. Thank you
