called my company asking for one person, I said we're not interested. Then called a second time asking for another person, told them again NO THANKS! Then called a third time at which point I just put the phone down. What part of "no" don't they get? Some scam involving diamond investment.

Called this morning, did not introduce themselves. Just looking for the owner of the business, who was not in. Caller did not want to leave a message. I looked at their website (http://hardassetcapital.com/).  They are an invest company dealing with diamonds. Perhaps trying to get others to buy in?
