Amazon India — accu chek safe t pro glucometer (multicolor)"

This product was paid in advance with the hope to get an early delivery for my patient. My app is showing "product delivered physically" to me on last friday, although neither the agency send me any message or they physically delivered it to my address. The customer care people could not provide me the contact number of the delivery boy or concerned agency. This is a very poor show from amazon. I am totally frustated. I shall think thrice before putting any order here.
