I checked this website on Trustpilot and I saw this which I believe should be summed as a a poor rating:

There are plenty of legit gambling sites on this forum to wager and to place sport bets, they are the only ones that I trust while if not on this forum, I will make further research.
According to the further researches I did, MyBookie.com is not a good gambling site.
I haven't heard about the casino either but it's a good thing you where able to reach out to the support, I think there's little or nothing the forum can do to help you retrieve your the account, so if you say it's calling the support is the only way then try to do that as early as possible, just figure out a way, if you have a trusted person in your country you can talk to them and make them call in your behalf.
If the issue is resolved, I hope he should not use the site again, check the Trustpilot reviews and see what I am talking about. There are many gambling sites that we can use which are legit and also very trustworthy.
