MoolChand Hospital — clarification letter not provided

Address:

Lajpat nagar, New Delhi, Delhi, 110024

As requested by my tpa, i request moolchand hospital for a clarification letter on moolchand letterhead for discrepancy in discharge date and billing date.
I visited more than 10 times and after multiple follow up i didn't got letter. I got reason that because i was given discount, moolchand can't give me clarification letter. Apart from this multiple document of hospitalization (Bill, discharge summary) is having discrepancy.
