Christian Medical College — Covid suspect ward not taking care of patients

My father admitted to hospital due to breathing issues on August 25th 2020 at 11 pm. On 26th he was taken to covid suspect room around 10 am and wait to get covid test result and they did not allow anyone to see my father. 11.30 am my father called to my brother number and he said doctor not giving water to him. After that my father ph got switched off... I called to CMC receptionist to switch on my father phone around 12.30 and she said that my father is doing good and had is lunch and going to switch on his ph but they did not and we called them again and again to switch on.. Around 4.30pm we got a call saying that my dad passed away due to covid. Unbelievable. Why they switched off my father ph and not switch on in-between 12.30 to 4.30. Something goes wrong there. Please give us more details about what really happened there.
