Airtel — My Number Showing invalid

Address:

Hyderabad

Hi, my airtel number is [protected], which i was using it for more than 15 year’s, recently i moved to UAE for visit for 6 months and all of a sudden Airtel deactivated my number and showing as invalid number. Moreover just 3 months before i have recharged it for a year package. How come they can for this I don’t know. Moreover this number is linked to all my bank accounts and airtel is harassing the customers in this way..

Please help yo get my number activate
