India Post — delay in emi payment

I send emo every month to my brother for his medicines & the post office at his place delays it every month by seven days sometimes more. The postman when brings it say it did not come to the office when clearly it shows in the tracking system it has been received. Other times they tell my brother to come personally to pick it up. Emo (Amount shall be delivered at the address by postman).
