When will the courier person come for pickup?

"We use the fastest and the most efficient courier company, Blue Dart or Delhivery, to pick up units from our customers to expedite the process as much as we can. There is no way for us to give an exact time as to when the courier boy will come to pick up the product; they generally come between 2 pm-7 pm to pick up the product. Also, the courier company does not share the contact details of the courier boy who will be coming to pick up the product."
