I was smart, I used a debit card which I fill only when I am about to make a purchase. I actually had to call my debit card company, cancel my card, and get a new one because every time I turned around Magic Jack was attempting to take money off of it, and this was AFTER the original agreed upon purchase price had been paid.
They sent me several e-mail stating that they did not receive their payment, but I know that is not true because I have the card statement to prove it, and I informed them of such and provided them with the information they needed to verify the validity of my statement. Six (6) months later, my service stopped working and I was unable to get it to work again despite being told that my account was in good standing.
I will never do business with these people again.
