I purchased a prepaid $25 card on February 24, 2005. I did not need to use my card until today, March 24, 2005. I tried using the card and it would not work so I called AT&T. I was told the card did not work because it was not activated when shipped. I needed to add this card today! or I will lose my minutes. Anyway, I called Amazon and they knew faulty cards were sent to them but not all of the cards in the batch were faulty. It would have been nice if they could have sent an email or letter to all the people that received cards from this batch. This way you could check to see if you received a non-activated card. Now I have to go out and purchase another card today plus wait 7 to 10 days for a return shipping label to send the card back and then wait to recieve my $25.00. I would suggest to anyone that purchased these cards from Amazon or any other place to check them before you need to use them. Not all of us have the time or the extra money to purchase a card at a monents notice. When all they had to do is inform everyone that got a card from this batch. POOR Customer service from both AT&T for sending non-activated cards and Amazon for lack of notice to buyers.
