Myntra.com — refund not processed for over a month

Address: 384-A/2, STREET NO 16 EAST AZAD NAGAR, 110051

Hi, i have placed an order on 28th september for 4 jeans.
Out of which 2 jeans are of exact same price i. E. 1292.48 each.
I have cancelled 1 product before it was shipped, so the amount for the same was credited back to my account on the same day, u. E. 28 sep.

But for the other one, i have received the product and then requested for return as the fit was not good for me.
Return was done on 30 sep and i received a mail confirming the same.
It's been more than 1 month now and the amount is not yet refunded.

Everytime i call myntra (2-3 times i called), they always give me bank reference number related to the cancelled order of 28th.

I've explained them many times that there is one more order of same amount which is returned on 30th sep so refund on 28th sep is obviously not possible, but they are not able to understand this basic thing and keep telling me that amount of 1292.48 is processed on 28th (The cancelled product).

But where is the other refund of same amount 1292.48 (The returned product on 30th).

Below are order details:

Product name;
1. French connection men blue slim fit mid-rise clean look stretchable jeans - 1292.48 - cancelled product - received refund on same day i. E. 28th sep

2. French connection men blue slim fit mid-rise clean look stretchable jeans - 1292.48 - returned product on 30th sep - refund not yet received (31 days passed now)

See point 2 above, i need refund processed for that one. Please don't get confused again because of same name and amount.
