Airtel Prepaid Orissa
Lost airtel sim, but not able to deactivate

Hello Sir/Madam,

I have lost my airtel prepaid number 8018440401. I had contacted airtel customer care to deactivate this number. But the number is still working (the person who has my number is using right now).

Now customer care is not reachable in their numbers and as per our last communication the number is not mine. How is it possible that i was using that number since beginning and now they are telling this is not my number that's why they won't deactivate it.

The person using the number right now is misusing my number and i am helpless to do anything apart from giving miscal to my own number.

Please help.

Thank you
