Cashify — APR Voucher Is not getting redeemed

Hello Sir,

I hope I landed to the most trusted portal for consumer complaints against any fraud. I got two apple coupon from cashify after selling a phone, but it is not getting redeemed.

I am fed up with their customer care support also, they are not able to solve the issue at this point.

So I came to you, can you please help me in the resolution of coupon redemption at apple store.
