Neha — receiving messages and calls for billing after removing the connection

Address:

7th main, Bangalore, Karnataka

Ttn keeps sending me bills and keep calling me.. I have already info me twist that i have removed the connection in 2015 only. But still they call me regarding the bill. When i am not using the connection how can you send me the bills. When i am not taking any net packs or doing the recharge from so many years that means i am not using it and after information also calling me thousand times.. A lady she called me from ttn n i already told her that i am not using it.. Also told her please stop calling me 1000 times and she said that ya mam sorry for the disturbance will not call you again.
Its been more than 4 years i am not using your ttn connection.. Then why i am getting calls and receiving message.. This is harrsment. I have already block ttn so many numbers still they call me from different different number.. Dont you guys know how to work.. Dont you guys know your responsibility. Of a person is not using your connection from so long still you'll make bills for no sake.. And after informing that m not using your connection.
