Who called from 3018829959

NCO financial collection

They call and hang up and want to say some [***].

They keep calling all times of the day and don't leave a message, I don't answer numbers I don't know and never leave a message.

I called this number back because it kept calling me. It was a financial institution on behalf of Consumers Energy.

Don't know this number and would like for it to stop calling !! Answered it once or twice and I get a *hang-up* responce .... SOOoooo, tired of it ... It has been going on for months now and at all times of the day!! Really need it to stop ... I work nights and sleep days ..!!.. Have a home-based business so I can not turn-off my phone!! How does a person make this come to an end???
