Just got a call on my cell phone from the same number.  In the past when these people call I press one to speak with a live person and make goat noises.  They tire of me and eventually hang up.  This way, I can amuse myself and annoy them instead of the other way around!!  Just a silly way to get back at them.  Today I didn't feel like being a goat.  LOL  I just went online and registered my phone number with www.donotcall.gov.  Hope this will help!!
