Receive phone calls from this # multiple times, have only answered twice and there is no one there. I've just stopped answering

I didn't answer, tried to call back number was always busy. Really don't know what this is?????

Automated message calls placed at least weekly to my cell phone during business hours. ENOUGH!

Said I have done something wrong

They called me and didn't leave a message. I am waiting on hearing back from a job and thought it might have been them. I called the number back and no one answered. The whole system in calling them was strange. Now I see, from other reports on here, that this is some strange and annoying company calling. I am sure that they will call me back now and that it is not easy to get off of their list....
