Sorry to hear about your problem Auchan.
I would also like to inform you all to be aware if you plan to call overseas using pccw calling cards. They charge you much more the amount other cards will Charge you.
On the Dragon phonecard I get 4 hours of calling time to Spain with 100HKS. With PCCW they only gave me 6 minutes! I felt really cheated. Especially since I went to the trouble of purchasing a card when I could've called from my regular phone and get charged the same insane amount.
I also asked at the guy behind the counter in 7/11 when purchasing the card and he said it was a really good card (obviously he didn't have clue)
Just a warning for you guys to stay away from PCCW when possible... they will steal every penny you have! In my personal experience, it is trully a bad company.
