I ordered important grocery item on 1st may 2020 (Thank you for your reliancesmart.in order[protected]w ; the order will be delivered by[protected].)
However, the incorrect few items were delivered. I have made numerous calls for the refund of the remaining amy but yet no action has been taken. How hillarious the service could be... Can't believe i hv to wait for my own money for more tha 15 days. Would u simply wait for the money, if i owed on u?
