Received the call twice but they didn't leave a message. I called back with caller ID turned off and an operator said call could not be completed as dialed. This means they are not honest in their business. No caller ID was listed either, so they do not want you to know who is calling.
On a daily basis, there are numerous calls from this "unknown" number, on my home phone. Not once, has a message been left. I'd appreciate it if they could stop calling my house. It's annoying to my family and I.
