Manipal Hospital — Issue in Billing

My mother was admitted in Emergency with MRN 351443 on discharge i got bill wherein X ray charges was posted. on enquiry they said x ray was done, when i refused and asked for report then after some hours they refunded the amount saying by mistake it was posted.
There are wrong practices going on and if we dont check bill unnecessary charges are posted.

I need apology and compensation else the same will be escalated.
