STRUGGLING TO GET CO PAYMENT BACK

I had a procedure on the 1st of February 2024 and had to pay a copayment which the hospital also paid now my co-payment needs to be refunded and every time ai call there is stories.It looks as if the finance department is playing the fool.They were very quick to ask for the co-payment on the day of the procedure the nurse even wanted me to leave the room before my lift arrived.I will never ever go there again.
