Who called from 6367421148

I answered it and he asked to speak to whoever the owner of this phone number was. I told him no and he could take me off of whatever effing list they have me on. Then I went to Sprint and blocked the number.

Claims to be a research company.  Called me at 5:50 Sunday night.  No more answering this number.

Caller ID said SSI, no message left.  Callback got a recording claiming that it is a research organization. The creeps called 8:40 P.M.

Tried to call back and the message said "The number you have dialed is not in service. Please check the number and try your call again. Thank you." No way to verify who it is by returning the call.

Received several calls this week with no message left.  I called their number and they identified themselves as SSI a market research company.  They said I could opt out of future calls if I sent them and email with my phone number.  I think I'm filing a complaint on this one.
