I have received a call on 23rd March 2014, from Visa card and they have offered 20% cash back linked with my credit card. I have not received any pay back card like that still now. I have received some voucher but it does not worth rs 500. The company charged 7999 Rs for this. I have seen in my back transaction the company name as VEE ESS Infosolutions. Can any one help me on this.
