AMRI Hospitals — delay of blood culture report

Address: KB 24, KB Block, Sector III, Salt Lake City, Kolkata, West Bengal, 700098

My father admitted on 31st January, 2020 with liver abscess under Dr. Sudipto Ghosh(Gastro). Liver aspiration process was done on 1st February, 2020 and the fluid was sent for Rapid Blood / Body Fluid Culture test. I supposed to receive that report on 6th February, 2020. But when I went to collect the report on 12th February, 2020 as I had an appointment with Dr. Sudipto Ghosh(Gastro), I asked to wait for 30minutes. The report was not ready. The authority could not even give me proper reason for the delay. I had to visit the doctor without that report. When I came back again to collect the report, I had to wait another 20 minutes. This kind of mismanagement is not expected in a medical sector. Who’s going to pay for this harassment?
I need a proper explanation with the details. I have attached the supportive documents. Please take a prompt action against it.
