wow… $17k in the hole… that really sucks…
After reading your side and theirs at great length and following the PM correspandance you had, here is what I would ask BETCRIS
Was the money wagered and lost? was the money withdrawn? This is important to know as if the money is wagered and lost then you may be able to argue to get the funds back?
Did you use the same computer everytime you wagered? hence you can argue a different IP address.
Can you get an old history of action of how much money you deposited and wagered? Basically proven what happenned was out of the norm for you.
Rather than getting anti towards them try making a counter offer such as asking them to give you the funds back with a small rollover requirement. See if this has happenned to other former BoS members and if so this is not an isolated case and you have a chance of getting somewhere.
Sportsbooks receive hundreds of calls a day saying they did not wager the amount when they did just to see what they can get back and BetCRIS probably has come across numerous cases like this. So you need to arm yourself with ammo if you plan to pursue this and work with them where you can.
Also in the future all of us need to protect our usernames and passwords and avoid using internet cafes, pubic access points, wifi etc when checking stats, gambling, online banking etc…
This is my two cents and my opinion on this.
