State Bank Of India [SBI] — Got a fraud call from online sbi

Hi,

Wanted to inform you that there was a fraud transaction made on my sbi credit card 2 weeks back regarding which i had filed complaint on different portals and forwarded my complaint to sbi as well.
Today, again i got a call from[protected] number saying they were from sbi bank and they wanted to credit money of rs. 5000 back to my account for fraud transaction. They wanted me to tell my card details (Card number, expiry date & cvv number) which i didn’t tell them. They told me that they were calling from sbi and if i want i can cross check their number as well.
I checked their number online and it was actually a toll free number from online sbi. https://www.onlinesbi.com/personal/contact_us.html
This was actually the fraud call and when i called my back (Sbi card) they said that they don’t have anything to do with online sbi as they are completely different entities and their behaviour towards me was really rude.
Being sbi card holder, i feel so unsecure now. When we complaint bank they don’t respond and they don’t bother to treat their customer well.
Please help me here.

Thanks
