No message. I have a new cell phone that work furnished me; my personal cell is not a secret, so not sure who had the number before me.

So many words posted and yet no truly useful information about the call or caller.
Obviously you did not answer (regardless of which of your phones it came in on) since you let of go to voicemail.  You seem to hint that you think the call may not have been meant for you, but since you do not answer calls, you will probably never know.  Second guessing what an unanswered call might be about does not help anyone.  Next time they call, answer the phone and actually find out what it was about, then you can possibly post something worth reading about.

OK, so this number just called me and it came up as "Account Services". I have been getting "Account Services" calls every day for the past week and always from a different number. I did find out this particular number is from a place called MCM (Midland Credit Management) and they are a debt collector. I don't have any outstanding or past-dur debt so I don't know why they are calling me unless they are looking for my bro-in law. He has nothing but ignored debt and listed me as his contact.
