told me they were with my credit card company, I hung up. they called back within 45 seconds.  I explained I do not have a credit card, we quit using these years ago.  the woman on the other end was positive I had a credit card, I explained I don't, she got very belligerent and I informed her I would report this number to the do not call registry. she had a few choice words for me and hung up.

Got a call frorm this number. Did not answer it. Just trying to find out who it might have been.

Answered and also heard "it's not a valid extension" from a recorded voice.

Collection scam for bogus credit cards

If You Don't Know The Number, Don't Pick-Up ? Duuh !
