Flipkart — Wrong product/ failure to refund

Address:	East Sikkim, Sikkim, 737101
Website:	www. flipkart.com

Hi,
I ordered Hook book cover for iPad Air 16 April 2016 (OD[protected] amounting to Rs. 1349). But on 26th April instead of what I ordered, an iPhone cover was delivered to me. On 28th April I submitted a return request and received an assurence that return of the product and refund would happen in 10 days. Yet after waiting for 21 days the return and refund did not happen. So on 17th May I called flipkart customer care[protected] and was given an assurence that my issue will be resolved within 24 hours. But nothing happend and again on evening of 18th may I called again and again I was given assurence that I would be called a flipkart agent in 24 hours but even after waiting for 6 more days nothing has happened. So I called flipkart again today asking for reason for not happening of pick pick up of product and giving me the reufund. I am given yet another assurence that my issue will be resolved in 24 hours. Please help.
