This 4154099059 just called and did not leave any message.  So I called them back and it said a non service number.  Well, a scam alright.  I just block and spam them :).

Called them back and spoke to a woman who said that there was demand for my services then proceeded to ask me what I did. My answer was that she should know what my services were if she was calling me. If she didn't she was pretty unorganized and was doing a poor job.  She hung up.
