Just received a call from them this afternoon. They didn't leave a message. Checked this website to give me some idea of what/who I was receiving calls. I'm on a do not call list already.
I also received a call today. They left no message. I returned call and was told the same a Bonnie (see above). I selected 2 to be added to the DNC list and waited a few minutes on a silent line!! I added this number to my reject list on my phone.
