Airtel — I'm complaining about the fraud calls that are made in the name of online KYC.

Address:

Barrackpore, Kolkata, West Bengal.

At first there's a message sent to your mobile number that KYC has not yet been completed and if not done within 24hrs then your number will get simply blocked.
There's a phone number provided where you are asked to call. When you call that number, a person asks you to download an app " KYC Quick Support " from Google Play store, which is not the full name of that application. That app is used for screen sharing purpose and not for KYC. Then you're told to make a recharge of a least amount i.e., ₹19/- or ₹21/- through online mode. They simply view your card details though that screen sharing application and take all your money out from bank within a fraction of seconds.
Beware of such fraudulents. I've saved myself. Please stay aware.
