American Health Solutions Annoying continuous calls, even throughout the weekend Internet

These people are relentless, I have been called numerous times. They just called me this morning 10/31/2015 which is a Saturday 3 times withint 15 min. I called back the first time to find out who was calling and hung up so I could look up this company. The first thing I found was rip off report, so as I was reading it they called me back. I answered but no one was there and hung up. They called back again I answered & they asked if I was there. I asked what is this about, they said who they are and I answered that I did not request any kind of insurance. She said oh, ok and hung up. But then they ended up calling back again but a different person was there. Next I started getting calls from a different number entirely. This is very, very, frustraiting. One other thing when you talk to bussinesses usually you will hear maybe people talking or typing in the background, well the background noise of these calls are very loud, like there in a small space with machine or fans/ air conditioners running. Its so noisey that the voices of the people talking are hard to make out what their saying.
