Shine.com — Receiving fraud calls in the name of Shine.com

Today I got a call similarly and got trapped by paying 3441/-. I called the bank to get it charged back but it was too late. They confirmed that they were from shine.com. Even truecaller display showed as shine.com. And now i dont think if a genuine shine.com executive calls also the people will accept the call and trust them. Request Shine.com should take some action on the same.
All calls were from Delhi and the People who called are :
1) Vikram Singh - [protected]
2) Amit Saxena/ Deepu DPS - [protected]
3) Rahul Gupta - [protected] (their manager it seems)
