I saw the # and called back. Ask who the company was immediately was put on hold to see what they were calling about. Then the same lady came on rambling about my defense attorney and some legal matter. I said I had not ever received anything and did they have proof. Well they have the information in their office here is what she said. I told her I had never received anything or had been served, she said she wasn't going to argue with me and I said me either and hung up!

Had a missed call, they left a voicemail saying they received "a complaint" but the caller did not leave her name nor a company name. Very suspicious. I won't be calling them back!

I just got the same call.  Has to be a scam.  When I said "wait, what?", she told me not to be rude, that she felt like I was interrupting her.  I laughed and hung up.

Just a message stating that there was a complaint

Just got the same call, didn't answer, came here to check it out.  On my spam list now.
