I have gotten multiple calls from this number and I've just not answered.  Today (7/11/2017), I was on a call, so I sent this one to voice mail.  They kept calling, kept calling, kept calling.  I finally answered and said "I'm not interested".  The gentleman got huffy with me, insisting that he wasn't selling anything and that I had insulted him.  I asked what his purpose was and he wouldn't say.  He just said "how do you know you're not interested if you won't listen" and was irritated that I insulted him.  I finally hung up.

Called the hotel I work at and said they wanted to leave a message for a guest by the name of Simpson that was going to walk in and book a room for the night. It was the strangest message ever with just numbers in the millions. Asked a few questions about the hotel and said he will call back later and book a room himself. Freaked me out so much that I put the panic button around my neck just in case.

Claimed to be calling from Dell but was clearly not. Foreign accent but gave a very British (fake) name. Terminated the call and blocked the number.

East Indian man named "Sam" wanted to speak with one of our Directors. He was pushy so I started to ask who he was, what company he was calling from and where in the world he was calling from. There was a screaming woman and children in the background which was strange. He was very pushy and said just to put him through. I told him to stop calling because he will never be put through to anyone at my company.

Called our business advising they are from Intel, they wanted to speak to someone called Mark. They were arranging a webinar. No one works for us called Mark and she had a loud TV on in the background and I struggled to hear her.
