I have deposited over 13 BTC on 1xBit account's BTC wallet and in return, the present day they treat their customer who are supposedly given VIP status as rubbish as I am denied any bonuses or promo points fairly even after making deposits consistently. 1xbit has dissapointed me greatly, I will not recommend you to visit or use this bookmaker until they resolve the quality of how they treat their customers!

I really really think there is a typo in your post, i hardly believe you deposited 13 BTC in a website, just like that, with no background check and so on.
If its true, its your own fault ...
