I had ordered product with the above order number worth Rs.329 on Amazon 15/12/2016. It was delivered on 20/12/2016 and returned 21/12/2016. I haven't received the refund yet. I have called the customer care thrice in past 10 days but there had been no follow up. They have been not able to provide any reference number. They only claim that they had initiated refund from their side but they never give me the reference number so that I can cross check with my bank. I request for the redress of this issue as soon as possible.
