Got delivery of pulse oximeter on 25 may but it had scratches and was not working either so requested for a return & picked by executive on next day morning, but when ever I call the customer care for refund they say they ll refund the next day surely.
Even after 45 days Still haven't received my refund amount.
I sincerely request to help me with this
