Ive had an account at intertops for more than 11 years, but I am in Canada and have not requested a withdrawal lately.
they have been around since 1983 and were one of the first (if not the first) online since 1997.
Like many others, they may be having some processing issues which may mean a waiting period before you get paid, but I dont think you have anything to worry about.
If you run into problems at any time, feel free to fire me off an email, to
sportsavant@therx.com and I will look into it for you.
