calls all day, all night, very annoying

Apparently was a recording pitching home security systems. Said to press 1 to speak with someone or 2 to say you already had one. (I didn't press anything)

Caller from this number identified himself as Daniel. He has an Indian accent and contacted motels in our chain, Budget Host Inns. He said he was from the corporate office and was shipping t-shirts to the motels. He asked for telephone numbers at the property and referred to some kind of codes. This is a scam. Our corporate office did not issue any t-shirts and has no representative like this.

Keeps calling my cell

They leave no message and when trying to call back it says number been disconnected or no longer in service. I WANT this to stop due to this # calls me several times a day!
