Airtel — sim deactivation of airtel bharti

Address: Rohtak, Haryana, 124001

I have number [protected] of airtel number for my startup company. But i had to put the startup on hold so i was not using this number. I went to near airtel care center but they were reluctant to help even. My email id and other account get blocked as otp is not coming. Please resolve this problem. You are humbly requested to what need full. I shall be very thankful to you for that.
