I missed the call and when I called back it just rang busy

found this on my call display but there was an automated message saying to call back +1 866-463-9161 and gave me a reference number. sounds like a collection call but no idea who it is because I dont owe any debt.

They kept calling me and said they were looking Andrew More???!!!I dun even noe who dat is!!!Simply annoying!!!

They called me on a brand new cell number. There was no answer when I answered the call. Will not be picking it up from now on since it appears to be a collection agency.
