Hi is boomerang.bet trusted spottbetting site or scam?

I have problems on their site I cant change mobile phone because my mobile number is 9 numbers long but at their casino  I can write only 8 numbers of mobile phone.Also I cant change Nathionality by myself I need to contact support and when I do it they write:We hope you are well!

We inform you that your issue has been resolved and the data should be displayed correctly in your profile.

So I asked them to change my phone number and Nathionality but they didnt but I cant withdrawal my money without phone and nathionality info updated on my account so I am worried that boomerang.bet is a scam.
