Address:

At. Post Kelwad Ward No 4 MH441112

I have oder a shoes for me on 29 August. It received me 4th September. And I have pay a amount of shoes from Flipkart pay later, as we know we have to pay Flipkart pay later bill on or before 5th day of month, so I have paid that shoes amount to Flipkart pay later on 4th September to avoid panalty, because the amount of shoes will be returned after 5th of September. So now I didn't get refund of that shoes on my account

As mathematical
I oder item of ₹459 -29 August
By Flipkart pay later ₹459
Balance in Flipkart pay later ₹ 41
Received on -4th September
Return on 9 September
But bill generated on 5th September so have to pay on before 4th September to avoid panalty to Flipkart pay later - ₹ 459
Now may Flipkart pay later limite is 500 as usual
Total pay for shoes =Flipkart pay later 459used to buy + 459 to pay Flipkart pay later bill before panalty date.
=918
But the amount of shoes which will be returned me after returning process of shoes to me or in Flipkart pay later it not show
