Grofers — no refund and return on missing and bad quality product

I have order many items and got delivery on 13 jun and found some item missing. Told by delivery boy plz contact customer care for any return or refund. I have contacted on same day by email (Only option available) and got reply we are working on your issue.

After that i send more than 5-6 times email and every time same answer and no one called me and no response on return and refund process.

As two items is missing and 3 packet expired product delivered. Today is 30th jun still no one care about customer money and time.

Such a worst and third class service provider.
