The same has happened with my mother, and doctors named in the complaint were also treating my mother for low BP and diabetics. They said various reasons (dengue, bacterial infection, kidney failure etc ) day by day the situation worsened and on 10th day died due to negligent treatment.
Only the reception and 1st floor is well maintained bcoz OPs visit daily and other places are similar to very cheap hospitals no ventilation, no AC, no cleanliness.
What I observed during stay is they say dengue for all cases, request blood and then put on ventilator, dialysis. After a heavy payment is done they declare as dead. Totally unethical and unprofessional doctors and business.
