Useless hospital

Hi All

This hospital is the worst hospital ever I was there a year ago for kidney stones however the assisted me well in the emergency section for a short period I stayed there, never the less after 5 months I received an sms saying I owe them money in which was settled in a month and today again after 1 year I get an sms saying I owe them money, when I tried calling the accounts division they like so useless to even answer a call claiming to be busy doing useless sms to people who don't even owe them money I really feel the accounts department should really be jobless as they have no clue who owes them money and who doesn't....they don't even check when the accounts paid up and allocate the payment for the correct account.
