I got a call just now, 5th August, 1:34 PM from a lady claiming that she was from Vodafone. She was calling from the # +91 9769656283
She asked me if I wanted to switch my phone to Vodafone.
When I told her that I am already with Vodafone, she cut the phone.
I am not sure if this is a phishing scam to get my personal information from me, but needs to be investigated.
