I have booked a bed and mattress in studio pepperfry, Indiranagar branch, Bangalore.As per the executive's advise I purchased mattress, which is not at all fit for the bed, I telephoned customer Care unit and raised complaint, they told me we take the return, because of executive's mistake...if she advised me correct one same day, I would have purchased suitable mattress same day...but executive wrongly advised me...and I paid all the amount same day..that is hard earned money..they have taken the return after so many days conversation with their customer care...today(19.04.2018) I have received the return money... without my mistake...why should I have to pay money that much earlier...and without informing me they told they already closed the case...over phone...how would I know...it's almost more than a month...right now I am mattress less, why should I suffer for their mistake and nothing they have given me compensation and not even interest paid to the money, which I paid them at the time of booking...how much mental agony and stress I have faced only God knows
