Magicpin — voucher earned in refer and earn not available

Address: Indore, Madhya Pradesh, 452001

Website: Magicpin app

I got an amazon pay voucher as a part of refer and earn program which i am unable to redeem as the vouchers are not in stock. I waited for about 5 weeks to redeem the same. The coupon code that i received got expired yesterday and now i will not be able to benefit from my referal. Because of this i will suffer a loss of 500 rupees amazon pay balance.
