OP account is a new one but I am still curious as to how OP got to know about this platform. It is either OP is an old member here patronizing 1xbit/1xbet  and he has been with them for a long time and upon his account being blocked, he has has to disguise himself to lay  complaint and does not want anybody to know his real account here. If you have long been existing here you should have seen the flags and tag attached to promoters of the 1xbit/1xbet promoters.
They are scam and I am sorry to say this, I do not think you would get your funds back and also sorry that their is no possibility that you would get any assistance from here because it is a well known information here about the activities of the scam casino called 1xbet.
