I have to side with Bryan on this one. There are too many things that are just plain fishy:
1. The screenshot of the T&C with the Date/Time window. Easily faked, and who does that? Who opens up the Date/Time window when taking a screenshot? Furthermore, this screenshot only appeared AFTER the player was asked if they had anything proving the date. It's the equivalent of changing the date and time on a camcorder and then videotaping some "evidence", but in reality that date and time are meaningless because they can be easily manipulated.
2. This player staked their entire initial balance on a single number in Roulette...and won?! Assuming player-friendly European Roulette, the odds of this happening are 1 in 37 at each casino, or 1 in 1,369 combined (0.073%). How someone can escape a 97.297% chance of losing their entire deposit in one shot, twice in a row, is far beyond the scope of my own personal experiences with even the best of luck. Obviously it can happen, but with those horrible odds it makes this situation that much more suspicious.
3. Whenever there is a gray area in the T&C's, how difficult is it to go into Live Chat and ask for clarification? It takes 5 minutes or less, and you can take a screenshot of the chat window and/or answer "yes" when you are asked "would you like a transcript emailed to you?" at the end of the session. It's that simple. Some people might say that you shouldn't have to do this, and that it's inconvenient. Well which is more convenient, a 5 minute Live Chat session to settle it before you potentially violate the terms, or a 15+ month pissing match that will never end satisfactorily for either side?
