Respected sir/ ma'am
i order a product worth Rs 1800 green board .
since it was scheduled for a delayed delivery, i decided to cancel it out
the refund has not been credited to my wallet .it has been more than 11 days now since i ordered the product and 3 days since i cancelled it .

i request you to look into this issue and solve it as soon as possible
