They call me but I just dont bother answering. What's the point

These sales cales are, quite frankly, insane. They dont listen to what I say, no matter how clearly phrased.

I got four calls today, each about an hour after the one before it. I called back using my home number but got a busy signal. When I call on my cell it does ring but no one picks up. So annoying!

I get calls from these guys all the time. The most annoying part is they actually leave a message that just has a bunch of noise and uses up my voicemail minutes.

They call me and ask me if I would be interested in some sort of weird credit card offer. I say no, then the next day its the exact same thing. Again and again.

Dont know why they call me.

I tried to call this number back and it was out of service. What to do?
