Shows up as "unavailable" on caller ID, no message left.  Unlikely that it's the IRS, Mayo Clinic or any other legitimate call.

Scam call received from this number, claiming to be my local hospital.  When I called back, they strongly urged me to pay a "doctor's fee" for a service dated 1/2 year ago, the bill for which was supposedly sent to the wrong address.  They repeatedly recommended I give my credit card info online before the collection agency was notified, even though they have my correct address and I have yet to even receive the bill.

I got mail stating that we need to call them to settle a dept - no name on the letter head - no name on the envelope - and if we were to owe someone money I would think that they them self would have sent us a notice not some company that answers the phone by hello - DUH!!!

I got a call and they said, please hold for patient services. ????? no clue and didn't have time to hold.

I don't care who is calling, if they don't leave a message then they are not legitimate.  No message = improper intentions.

I got a voicemail with nothing but on-hold music.

Ditto to the comment about if it is Mayo Clinic Patient Accounts, they should leave a message!!!

I get calls where there is a recording stating 'all their operators are busy and they will be with me in a minute.' Like I called them, when I didn't.

If it's true that it's from Mayo Clinic Patient accounts, then they need to LEAVE A MESSAGE so that people don't think it's a scammer calling.

This is from Mayo Clinic Patient Account Services.  This is not a scam.

This is from Mayo Clinic Patient accounts.  Not a scam.

Annimated voice asked me to hold for some financial associate. I hung up.

Got a phone message from a "Peter" claiming to be with the IRS.  Wanting infomration about a client.  (I'm a CPA.)  BOGUS

very suspicious misleading
