Who called from 2485562372

They call all the time it is a local number will not leave messages and when i call back it is busy??

keeps calling but when we call back just get a busy signal

Only answered the call because I was caught off guard by the 248 area code & didn't pay attention that it said unavailable, caller didn't want to leave a message.

bill collector
