Account under surveillance

[Former user]

I have encountered a problem while pinging to a expert after logged in, showing the message "Your account under surveillance " . What's that?

I have changed my android login e-mail()[e-mail] for my personal reasons which i have used for your account also and now i configured my android mobile with new email id. Downloaded your app and tried to login with the same old credentials, i am able to login but while pinging to an expert i am getting the above mentioned message.

Can you please look into the issue and resolve asap.

Thanks, Vijay.
