No.
At this point - why not name the book you entrusted with 350k - who stole your money.
Im presuming of course all of the wagers were losers (after all - why would someone stealing from you place a WINNING wager in your account ?)
When did this begin and when did you first notify the book ? Did you change passwords at any point once noticing the theft? What was the response received from the book.
Understand what you are suggesting here and that there will naturally be questions. Simply stated 99.99% of sportsbook accounts do not have 100k plus in them - so immediately you are in a small majority. Then to have your account hacked - again - small majority - but absolutely possible (especially given it’s a high value account). To suggest it’s the book stealing though - you really need to have some proof - and a response from the book explaining the bets made. They have a vested interest in security too and would certainly investigate - what have they said?
No point in “protecting” who you feel is guilty here - you posted and seem to have reasonable belief the book is the thief here - so name them.
Personally - there are few books I would feel “comfortable” entrusting with that level of cash - or anywhere near it - and those books have both a track record of honesty and security teams that handle a wide variety of problems. If someone were for example to say they sent XYZ PPH 50-100k - I’d be immediately wary of the story - just because a reasonable person doesn’t send that kind of $$ to a virtually anonymous stranger or shop. There’s a reasonable level of trust. Now if you say for example
Pinny - makes complete sense - many players DO trust them with big money - but no one else is reporting thefts there. Could be a rogue agent for all we know - or hacked account.
BTW - do you use an interpreter named Ippei ? I have heard rumors of some issues there involving gambling.
