I had purchased the samsung s7 from amazon.in for 12503 on 23rd sept but they had refused to provide me the handset playing excuse for it being out of stock . I had paid the money online via debit card . Even after i had confirmed thrice from customer care about confirmation of my order but still after all that stuff my order had been cancelled even deleted the record from my amazon account playing mischief . Pls help me out they had declined the order even after offering the deal and received the payment from my side
