I got this call last year and they debited my account with SBI. When I sent them mails for enquiry, they respond saying they you have to send the voucher with DD to their address. Once you send them, they will not get back and when you send them mails, they will give excuses and escape. The helpline number is not reachable at all.
Can somebody in Delhi trash those bastards. Plz dont get trapped into this scam.
