Flipkart — Cashback of 500 rs not credited

Website:

www.flipkart.com

I was supposed to get 500.0 rs back for my recent order Colorfit Caliber Smartwatch which must have been credited to my Flipkart gift card wallet right after delivery. Its been quite a while after delivery and I haven't received my money back yet. And when I tried to contact the hep centre numerous times they made me wait for so many hours and left me on read and even marked the issue resolved without giving me a proper response. Im attaching a screenshot of the order and cashback details kindly go through it for more clarification. This is such a scam kindly help me out to get my money back.
