Well you are seeing the pattern of a deposit then the coins are immediately moved. I'm not sure why they did it like that, but it was never a problem until that date 5/17/19. Normally when the coins are moved my primedice account balance would be credited. I would make a series of bets then I would withdraw funds.
I have found my a long message thread with support person Mladen, which I now realize is Primedice CEO and founder Mladen Vuckovic. He personally handled the missing 14.2 BTC and he credited my account with 15.1 BTC after 2 weeks or so of back-and-forth. He said "Looks like it was everything ok with your account. One of your deposits did not show up on blockchain." This is not true from what I saw on the blockchain. The deposits confirmed immediately on the blockchain. After this refund then he stonewalled me with regard to the other account.
maybe OP is using 2 accounts? and they have locked one?
I was using 2 accounts. One was username: gforce37 the other was username glapattack. Now they completely eliminated both accounts.
EDIT
EDIT** Also, I never asked for a bonus 0.9 BTC Mladen gave that to me of his own accord. I just want what is mine, what I deposited to *both* accounts. He can take back the .9 BTC if he returns my 9.8 BTC
