There is nothing worse than getting home from work to find an unknown number, probably just another tellemarketer but it sure is annoying! Their are days where my phone will go all day without ringing and days where it will ring off the hook. Gees, glad I am not home during the day to catch the calls. I did try calling back and it just gave a quick busy signal, in other words good cause I didn't want to talk to them either, they better stop calling!
