Fisher Investments. I gave my information, including phone number, to be able to download some investment information they offered; but I remember specifically clicking on the option not to receive any further contact from them. My spam-call blocking software on my phone blocked the call; but I always try to find out who the caller was, in case I might actually want to return the call. In this case, I don't.
This is FISHER INVESTMENTS. Totally legitimate investment firm that deals with individuals who have $500K+ to invest. If you're getting calls, you probably requested a brochure from their site and provided your number.
