Update: Situation was Resolved with the help of Dave Mason @DaveMasonBOL and Mark in security. I don't feel like it is necessary to elaborate in great detail, but a second security review did reveal a login from a device that clearly did not belong to me. The alleged login which I referenced was indeed not in the login history. I am not in the business of speaking for against gambling sites, I will leave that to others on this site. However, it is comforting to know that if you have a legitimate issue, there are higher ups at BetOnline like Dave Mason and Mark who are willing to listen to your concerns and sort through facts to understand the full picture.
Very good news.
Glad to hear you have your money.
