I received this call on my cell phone. I called it right back and it is a debt settlemnt company. I got a recordering saying it was Infinity

got a call from them this morning... i find it odd because i paid my bill from the collection agency yesterday...

Got a call from these parasites claiming I owe more than $500 for a CT scan I paid $353 for up front while at the hospital.  How can I owe on something I paid for up front?  It's completely bogus.
I called the hospital directly and they said they have an in-house billing department and don't outsource any collections.  Even more fishy.

CMRE FINANCIAL has called me twice.  
First time around they didn't have my correct address, and introduced themselves as calling from the hospital in question, so I updated the address over the phone.
Second time around, they called stating mail sent to me was being returned, even though they now have the correct address - which is basically their cover for not having sent anything.
Fishy, fishy, fishy.

All things taken into account, I'm considering filing a police report.

They are giving warnings that they will be sending your billing payment out to a collection agent.  But they are really nice they let me go on a payment plan. To pay may bill

Thanx for the heads up. I know EXACTLY who CMRE is our whatever the name of that collection agency is.
