Sorry for your experience. My cousin paid for 2000GRX on the 15th November, being the final sale. He received a mail acknowledging his payment, but didn't receive any token. This money they transferred his Ether back to his wallet. Another person also told me he received his money this morning. Try and be reminding them of your issue through Facebook, twitter and by raising a ticket with support. You should also know that they must be attending to many complaints. Good luck.

Bought a bit at round 1. Planning to get more on round 3.  I don't know why there is less interest to this token in forum. ICO sells really good
