My Response:
I am wondering why can you only refund Rs ***, why not the full amount which I paid to Airtel since * years, please let me know how Airtel is deciding that I should get only Rs *** instead of Rs ****?
Please provide me an exact reason or complete refund since services were activated without my consent.
Also why with every mail I am getting new Airtel Adviser why a dedicated adviser is not answering my questions, I am sending emails from more than a month, please provide me answers for my questions.
Looking forward to hearing from you.

Tarun

Now Airtel is not answering my questions even after multiple emails, I need refund for same which is Rs ****
