Received a call from this number on 11-7-7 at 8:40pm.    The caller was rude when I asked about who they were.

This is a market research company. They are often rude and rarely qualify anyone.

Called me two days in a row, asking for a "Ryan Dolph".  Says they are a market research company wanting to talk to "Ryan" about his interest.  After their 2nd phone call, I called them back and asked them to remove my number since it doesn't belong to any Ryan.

Funny thing is, even though not only with this caller, people have been calling my cell for this "Ryan" person, even though I've had the same number for months and haven't given it out to many people.  I'm thinking of changing phone providers.
