I haven't been able to buy the special offer for over a month. I tried to use two different credit cards, both "master card", but the screen where to enter the security code for web purchases does not appear and the transaction is denied. with the same cards I shop everywhere and I can buy the monthly card but the special offer does not. I contacted the credit card customer service but there is no problem for them and they say that the problem is with the site where I buy. I tried to use 4 different browsers but nothing. i tried to contactor twenty times hentay heroes support but they never answer me. does anyone else have these problems?
