I have been experiencing the same issues and cannot get them to stop. Two weekends ago, I called them back so many times, they told me to quite calling them. (haaaaaaaaaaa, how do you like that, eh?) There are MANY phone numbers that they call from. Some from Florida, some California, but none of them can be traced.
This attorney knows all about them and they just need our help to stop them.
