I don't think OP is shilling here, otherwise he wouldn't mention the withdrawal limit issue wich resulted in him losing all his winnings.
OP is not a shilling but has been forced to lose all the winning due to withdrawal issues on the site, most of the sites that offer such big bonuses and winning always have a withdrawal limit or conditions that are hard to be met which potentially results in the total loss on the players so I will advise before you play or deposit on any site make sure to have read the withdrawal terms and conditions.
Yes, he has got a problem and has shared it through the thread. He might've believed in getting a solution through our forum. If it is a reputed platform now he could've got an answer for it. This is something unknown and OP has added all details. He has added the list of withdrawal rejection from the gambling site. As said, it is a must to go through the terms and conditions before spending. I believe he is new to gambling, if not he could've got the patience to withdraw little by little understanding the consequences of gambling.
