Reebok — order Id od[protected] refund of 1870 not refunded after 4 months also

Website:

Flipkart

I ordered 2 Reebok track pants from Flipkart through debit card .Rs 1870 has been debited from my account for Flipkart order on September 14, 2017. On cancelling the order after an hour . The amount was not credited to my account even after 4 MONTHS now. The bank branch and the online customer care was contacted several times but they cant help it as they have not received the amount. I have contacted the customer care of Flipkart as well and received pathetic services.
They say it has been refunded but I never received the amount.
It has been 4 months and the issue has not been solved and I have not received the amount .I want that the query should be solved as soon as possible otherwise customer forum will be approached. Also there has been enough negative word of mouth for Flipkart since these kind of things are not acceptable from a brand like Flipkart and reebok.
