Airtel — rude behaviour from airtel executive

Address:

Chittoor, Andhra Pradesh

I got a call from a number [protected] at 3:33 pm today regarding the unpaid balance for a sim no. ([protected]). I told them that the sim got misplaced 3 months back and that we are not using it. She said the sim is being used currently. I asked her for the numbers that are being contacted on that number so that we can put a police complaint on that. She said it is being used for internet services. I asked her to check again if there are any call made from that number to any other number so that we can track who is using the sim. At this point, she started hurling abuses at me and asked me in a high pitch voice if i am mental. I disconnected the call. This is harassment.

I verified in truecaller and found that the name is swetha.
Can you please take necessary action against the offender?

Thanks,
Likitha
