Club Factory — unable to withdraw refund amount

I have ordered a dress from club factory on 28 august 2019 and got the delivery on 3 september but the dress material (Semi stitched) was not proper in size so i returned it. I got refund amount after deduction of pickup charges of rs. 90 (Never expected from any of the shopping site) in usd which was 6.7 usd while i paid in inr. Now i am unable to withdraw that money to any of my account or wallet. Ideally refund must be in the same mode by which payment is done.
