The phone rang, I answered; a robot-voice said something on the lines of ...

"Please don't hang up this is not a telemarketing call, this is a request to receive your medical grade brace."
I started to tune out of the speech, but I kept listening off and on. My ears were alert again when the robo-voice said,

"... to unsubscribe please press `9` on your phone."
I did just that and the call ended.

To be clear, I NEVER requested a medical brace, I truly don't know how these folks got my number nor keep pestering me about this. I hope they will stop calling me however it is unsure at this moment of time.
