Airtel — airtel number got deactivated

Address:

Bangalore, Karnataka, 560064

My airtel number got deactivated on 21 december 2018. I had recharged it on first week of dec for 82 days (448 pack). This airtel number was my only number which i was using from past 7 years. From two weeks iam visting airtel outlets to get my number reactivated but the only response i get is we are trying ma'am, it will be done by 1 or 2 days. 15 days got over and still no action is taken. Iam facing lot of problems, because this number was linked to all my bank accounts and other official things. I want my number back please help me out.
