Consumer Redressal

My Prepaid Airtel Number has been deactivated since 01 January 2021 without any prior information given to me. I reached my home Airtel Store by all documents and by sending email to Airtel Appellate Authority & Nodal Officer also. But they are not able to reactivate my number and sending me here and there, and Airtel Store are not able to reactivate this number because in their database no records available for this number. I am using this number from last 5+ years, and all my daily work are dependent on this number only like my business, work,etc. and all are impacting due to this from approx. 1 month. I am suffering mentally, physically, financially because of this problem as most of my work is dependent on this number. I reached Airtel twitter team, they are saying take another number we can't reactivate your old number. I don't know to whom could I contact to file complain to Airtel to get my number again.
