Cleartrip.com — Non refund for Cash Back offer

Address:

Thane, Maharashtra

I had booked tickets through cleartrip and they had promised me a cash back on my credit card. Subsequently I have called them at least 15 times and they have never bothered to get back nor refund the amount. All i get to hear is that they will get back after 24 hrs.
The names of the personnel I have spoken to are : Ashish, Sony, Shweta, Sunny Singh, Sanjeev, Rama Narsarya, Padma, Sanjeeth, Rajesh, Vinod, Sunaina, Rahul; D'silva
