I ignored the call as lately I have been getting telemarketing calls on my cell phone. But after 7pm, when I have free minutes, I called back, after seeing this page, & got the message others are talking about. It's not an out of service message. It says "the # or code you dialed is incorrect". The # has got to be a company # that doesn't take incoming calls.
I'm reporting it to the donotcall.org site. For those of you that have registered your #, I urge you to do the same EVERY time you get a call from these low-lifes!
