I would advise that if you have any coins in your blockchain wallet to contact support asap and explain what is happening and try have your account locked down so no payments can be sent.
Better still if you have your memoric seed (and you should) then recover your account via a VPN to hide your IP address and move any funds.
Do you have 2fa on your account setup?
Also what country are you from as this may be a legality thing from countries that have banned bitcoin, although that is a very long shot.
