Answered phone, no response. No message. Annoying!

Someone called from this number twice today one right after the other! Left only one message which only said "did you? did you? Man, how did it feel?' I blocked all future phone calls. Called them and it was Investors Business Daily.( I had ordered this publication in the past and must say I was pleased with their publication and service.)  A very professional man answered the phone. I told him what was said and he wanted to check my number. I didn't have time for all of that, so I just told him his number was blocked and not to call again. Not sure what is going on with all of this. Strange.

I receive a phone call from this number on average 3 times a week.  They never leave a voicemail.

Seems like they call at least once each day. Am too busy to return calls with no message.
