Amazon.co.in

I am talking about the refund of 2 jenatics jeans of worth rs 1990 on prime account [protected]@gmail.com . Refund was said to be initiated on 27 September but still I have not received any amount. I have contacted my bank but they are denying of any amount in my account and there is a proof of that attached to this mail. So look into the matter and give me my amount since a lot time has passed and still no solution and not your customer service is responding well
