Airtel — excess bill generated for broadband connection

My airtel broadband connection has received excess bill as compare to earlier bills. On calling to costumer care, i get to know that my plan has been changed on relocating to noida from gurgaon where as while shifting, airtel has confirmed that my plan will remain same.

This is really disappointing attitude from airtel. They have neither close my gurgaon connection and also activated new plan on noida connection.

I am using airtel from 8 years and using airtel broadband from 2 years but i have never expected such behaviour from airtel.
