They tell they have refunded the cancelled orders' voucher amount as the items that were ought to be purchased were out of stock of Rs 248.30 to the issuing source google pay but it's been more than a week but still amount hasn't been received..
I have emailed sent feedback but their reply is they have refunded to the original payment source but till date amount not yet refunded and they also tell to contact our bank but why it's delayed it should reflect within a week and be refunded right
They are delaying and it's our hard earned money, now we want our refund.
And solve this issue rightly
