Medlife - Insufficient items delivered

I had purchased * packs of * Dettol handwash refills each of ***ml from Medlife for a total of Rs ***. That said when I got my package and opened it to my horror I saw that the box contained only * refills instead of *. Actually, I had purchased * quantities of handwash refills each in a pack of *. When I contacted the company they were initially confused and stated that I have been delivered the * refills. What their customer executives did not get was that each quantity contained a pack of * refills. I escalated the matter and the company has promised a refund but so far no refund has been credited to me.
I just want to request the company to either deliver me the remaining refills or initiate a refund of Rs.*** for the same ASAP. I request the concerned officials to kindly resolve my grievance promptly. I will be very grateful for your assistance and guidance.
