I went to freodtert ER 1year ago and setup up a payment plan for my bill but my dog got sick needed surgery so I called the financial department to let them know I can only pay a certain amount for the next few months so I did. Two months later Freodtert Financial department called me and harassed me to pay what I owed or they will send my bill to collections. Froedtert hospital is nice when you walk in to the ER or clinics but when it's time for you to pay they are not so nice plus threatening you.
