Sorry, I never tried playing on that site I try though but it says:
"SORRY, THIS SITE IS NOT AVAILABLE IN YOUR AREA"
Very weird, I don't know who advertise them as reputable but from the looks of it, they may have some problems right now so I guess you need to wait. Not saying that they're going to scam you or something, but the possibility is always there.
Sometimes there was particular site who restrict from particular countries to be access and that's why you have those warn when visiting them however OP basically not advertised this site that he was asking help to the people because have withdrawal issue but unfortunately most of people at here does not have any experience to play on the site which OP mentioned above
