If it was a phishing site, how do you explain the following:
1) same message for address change appearing on my mobile app and on the browser
2) reward points updated correctly in their database; just prior to depositing, the lost bets caused an adequate increase in the reward points status, and this amount is still there.  I used the same page to deposit.  I'm no expert, but I would suppose if it was a phishing site, then the whole webpage would need to be a scam, not just the part which was related to the new address notification and the QR code.
3) they corrected the link for generating new bitcoin address after we brought it to attention, now this "new deposit address" button is working properly

It would be too big of a conspiracy theory all 3 above to be true.

I'm suspecting that many more had the same notification, not just the few of us, but either they didn't deposit to it, or deposited a smaller amount so they didn't feel the pain, and did not want to spend too much time trying to rescue their funds.  Even myself, I am a newbee in this forum, and I only joined driven by the search for similar cases where people had not been credited their deposits.  In fact, main purpose was to try to find a way how to reach FBC's support team  (since none of my messages to FBC's support mail resulted with an answer, which on it's own is a red-flag for me). 

Then I read jper3009's case, and I understood that TheQuin is their support, so I have a glimmer of hope.   I am waiting for TheQuin's response, but I see he has not been online for 5 days.  I hope my case will not take 8 months like jper3009    

Any other constructive suggestions are welcomed, but please don't put salt on the wound by just giving your opinions that it is our browser's issue or similar, since it is dismissing the real issue.   The real issue, is we need to get the answer from the support so that we know for sure what is the situation, and avoid speculations.
