Airtel — misguided and made a bill of 2444

Address:

New Delhi, Delhi, 110063

Hi there,
I'm payal makhija holder of some connections of airtel service provider from a long time.
I was cheated by one of your retention team member and a store (Address - b-1, ground floor, paschim vihar, 10063) by rs.1916
A few months back i was porting my airtel mobile no to vodafone (9599555*), i generated the porting number and suddenly i got a call from him saying he will be giving me the discount on my current plan and my plan will be now 349 infinity with same benifits. So i visitied the store to reconfirm.
Unfortunately i came in their words and didn't ported for which i'm bothering now with my different airtel no 7503308* because now outgoing calls for this number has been restricted.
I'm ready to pay the bill to start my other no services but i will not be paying 1916 cheated amount.
Also, nobody is ready to help me out with this not even you customer care department neither any store.
I want a strict action on this else i will be registering the complaint against you people.
Thanks
