Fortis Healthcare — Charging Registration again Fortis previous Patient

My Wife Sonal Pandey was hospitalized in Fortis Cunningham Road Bangalore, from 06-10 October 2018.
Now, today we had same kind of problem and we came ro Fortis LA Femme but they are charging the Registration again. What is the use of having hospital chain when we have to pay Registration with every hospital. Otherwise you say it is one time Registration, not sure that is only for a year or 2 year this is not mentioned anywhere.
I know this is clear revenue. But please do not cheat. Say upfront that you charge. We have left Max and started with Fortis but seems all are the same. Rather I should try once with Apollo.
Rs. 150 does not make huge loss. But here is the matter of words by hospital and their values.
