its the business office of Palos Hospital

It claims to be Palos Hospital.  When you call the number back, it doesn't go through.  I called the hospitals main number and used the menu to reach the business office.  I spoke with Bridget in the business office and she informed me that this robo-call is a scam and they are aware of it.

I was told the same thing.

They will ask you for your credit card information
