How to Recover a Suspended Tango Account

My Tango account with the email address www.sainarahman**@gmail.com was suddenly suspended on 27 October with a “violation” message on the screen. I was not given any clear explanation about what kind of violation I allegedly committed. I believe I have not intentionally violated Tango’s rules and I would like you to review this suspension in detail. If I made any mistake unknowingly, I kindly request a clear explanation so that I can avoid it in the future. I am requesting that my Tango account be reactivated as soon as possible or that I receive a detailed written explanation about the exact reason for the suspension.
