I just recently gave this app 5 stars, but i have to rate them one star now. I downloaded x2 blocks from the offer board. I had to unlock block 4096 which i did. I waited but did not recieve my coins so i submitted a ticket it kept giving me error msg, i completed the next task unlocking block 4m and getting my coins i contacted them this time it went through and they denied my request. No reason why the thing is i had to get past 4096 to complete 4m. Cheated me just like they all do
