Well this is their response:
Dear Lukas Kucera,
yes you are on post-paid howeve we needed to change the billing way as to many people just called once a month.
The system now will automatically watc your account. Once it is dropped below the Trigger ow set at Euro 10.00 you will be refilling at Euro 25.00 automatically.
If you like to change the trigger or refill amount please do so at the account panel once you have looked in at
www.gt-sim.com.
We trully liek to appologize for all the confusion but be are now growing at such a high level that we needed to do these changes to continue to offer our quality of service.
With best regards
Markus Hauschild
As I clearly wrote them that I going to report them as fraudsters to my bank as didn't authorised some transactions on my card. I was surprised by their inability to reply normally. As bought this card just in April, I am very unhappy. Therefore, I will fill refund claim for their charges. And advise you to do same.
