Flipkart — Refund for wrong suitcase

Address:

IIT bhilai sejbahar

Dear sir,
I had ordered new Jersey travellers blue colour polycarbonate suitcase under order id OD[protected]. But I got red colour polyester suitcase delivered today. When I tried to return it, your app shows that 75 rupees will be deducted. I said them to Kindly help me to return it without deduction of any fine because it is not my fault but seller's fault that he delivered wrong product. I am very sad that Flipkart is selling wrong products totally different from description. After mailing them again and again now they had picked up the product but cancelled my refund. They are not giving any money for the product picked up.
