There is a product which has been returned and the refund of INR ****, is expected. Website was updated with a message that a refund of **** is initiated and that I need to wait for *-** days, and the amount was not credited even after **th day, Again, after multiple follow up , they said, the refund was re initiated and that I need to wait for again ** days for amount to get reflected. This amount was again not credited and that now, even after multiple follow ups, all they are doing is buying time with no resolution yet. Its going on for over a month and there is no update. They are not providing any reference number or transaction number at the same time, they have updated their site with a message that refund is processed successfully.
