Sahyadri Specialty Hospital — holding security deposit of 5k against cashless mediclaim

Address:

Deccan gymkhana, 411004

The hospital has held a security deposit of 5k against my cashless mediclaim reimbursement claim for more than 90 days even though the claim was already sanctioned by mediclaim company. I am not sure why they are making practice to hold a security deposit from patient when the mediclaim company has already confirmed the settlement amount.
Horrible experience.
Why patient needs to pay hospital interest free deposit as a security. Who has given authority to these hospital to held such amount from patient without interest. This needs to be stopped.
