[Resolved]  Fortis Healthcare — Excessive bill and unethical behavior

My father (Tarlochan Singh) UID 10478504 admitted in Fortis Hospital Mohali on 2nd February 2021 due Cardiac Complaint. As per Doctor Rakesh Jaswal advice my father got admitted for Angioplasty and stunts treatment.
Before admission I was asked by Fortis representative about the Insurance. I told them my father covered under Bharti AXA Policy No GHA/Q1609888/11 EMP ID D-107 HIID 4698173 Member ID[protected] Health India Insurace TPA services PVT. LTD. I have also submitted the details for same.
After that the treatment o my father went fine and my father got discharged on 5th feb, 2021 and the bill was covered through insurance.
On 6th Feb 2021, my father again got admitted in Fortis Mohali, with uneasiness. Before the admission Fortis staff asked my about the insurance details and i submitted the same. Fortis started the treatment.
After week I got a call from Fortis representative that my father insurance is rejected due to some ABC XYZ reason and they told me meet the TPA officials. From them I got to know AFTER 1 WEEK that my father is not covering under Insurance. even i was getting the messages on my mobile that my amount is approved by Health Care India Insurance. How can this happen that after 1 week of treatment and after approval of amount from insurance, fortis Representative said you have to pay the amount of Rs. 6 lakh.
I told them why didn't your staff told this thing earlier when my father got admission. I was thinking that my bill was covering under insurance scheme, but Fortis told me this thing after 1 week when the bill was generated around 6 lakhs.
I also received the approval amount messages from the insurance company, later they said it was approved by mistake. If it was not covered under the scheme why did Fortis start the treatment and why after 1 week I have been informed,
If I got this thing going to happen I never ever thought of going to Fortis due to shortage of Money

I told them for informing me, instead of giving treatment. But it was late from Fortis Hospital and Insurance
This is drastic mistake from Fortis and Bharti AXA. i am going to file court case against both the parties
