I bought a calling card on UNIONTELECARD.COM web site. I selected their automatic recharge which provides for the card to be automatically recharged by $10.00 anytime the balance goes below $3.00. So this particular card and pin always has money on it. Upon checking the call history for this card over the last 2 months on the website I noticed several calls to Greece over the last 2 months that I did not make. Either someone hacked the site or one of their employees with access to client's online account was making calls on clients pin numbers and making it appear that it was made from one of the client's pinless dialing number. I complained to the company and they refunded me the cost of the calls I did not make. But its scary to leave your credit card number with a company that can be so easily hacked or exploited by their own employees.
