I believe if you have all the supporting evidence which you say you have you will be successful. I find some older fax machines which many companies still use give bad copies or perhaps you had a bad line.
Mail the supporting evidence in.
Now as somebody who visits Las Vegas fairly often, I hope you dont ever take up the game
Gambling $400 to win $50 even if you consider it a "sure thing" is a very bad bet
