My answer to them is a resounding NO, it is not cool. They charged me in BTC. I paid in BTC. They should honor their deal, case closed. If you bet on a football game, and you lose, you do not get to modify the bet after the game is over.
It has nothing to do with this thread but:
If you bet on a football game it happens once in a while that they modify or cancel the bet afterwards because THEY set the wrong odds on it.
Or they invalidate it because your bet was too large, or if you had bets that was "on both sides" ... etc etc.
Read the betting sites TOS sometimes and you will be scared...
They also give themself the right to arbitrarily close the accounts of "unprofitable" customers. (not everyone does but many do).
I have had 5 accounts closed so far: (sportingbet, bwin, stanjames, eurobet and 1 more i do not remember the name of).
The reason was that was not profitable or that i was betting to much on "wongly set odds".
