Airtel — excessive bill and in which my number hasn't been used

Address:

Bangalore, Karnataka, 560038

My airtel number [protected] isn't been used as i'm suffering issues from connectivity problem, my number is not reachable from past a week even after clearing bills on time, also have applied for family plan joining which isn't happened, and the store people are literally illiterate and cannot do their work, requesting the department to take strict action against such behaviour of company and its worst services against innocent customers
