Account reclaiming mail was showing error

I tried to recover my account by giving all dats. The problem is now that the other email address I want to link is not getting approved. I tried 4 emails always didn't go through. Verification code is receiving but this dialogue is showing 'please be wary of individuals claiming to the official team members who ask you to provided email address when filing a claim, as this may result in the loss of your account'. What should I do. Please help
