I called them back today. they keep calling my work phone...they are apparently a collection bureau and were looking for someone else. My suggestion is call them back after 9 am.
i get a couple of calls once in a while. never answer it and they don't leave a message. My husband called them back and it said please hold transferring then it hung up.
Get a call from these people atleast once a week at my job. It's a recording that asks for someone by name but they say it so fast I can't even understand who they want. I just hang up on them.
