Relaince Fresh — Double swipe of charges & no refund

Address:

Bangalore, Karnataka, 560029

Hi, I have swiped my Citibank CC for a purchase on dec 5 2015 from BTM area Bangalore Reliance Fresh & the representative told it has been declined & gave me a proof copy of sales reversal so i handed other card but when i saw my statement it has been charged & since i am following up with them no respond on emails even the customer care is helpless as the complaint was through emails.
