[Resolved]  Airtel Broadband — Incorrect contact number in database

Hello,

I have a airtel broadband connection in my name, whose bill reminders i receive on my mobile which is normal. Past 6 months, somebody has put my mobile number in their alternate contact number field. Now when due date comes airtel customer care leaves no stone unturned to abuse and threaten me to pay the bill that is not mine. I have complained to customer care many times, but they say I must find who did this mistake on my own and then ask those ppl to file a complaint with airtel, then only something can happen.

Nobody is willing to help. Can anybody suggest any way?
Can i use RTI against airtel in this matter?
