Interesting.  This thread has been dormant for 2 years, now here you are telling us how wonderfully easy this company is to work with.  a simple phone call and all is taken care of?  Why you even copied the ad from their contact page.  But the even bigger question is why are you posting here?  After all, you said you found them through their web site, not by looking up this number.  So you must have looked it up after you talked to them.  Which means that you knew everything you needed to know.  but you then looked up the number anyway and posted here.  Now why would you do that?

I never heard of them and they keep calling my parents. I had to change my number, they kept calling several times a week at work.
