they have called me on several different days. If I didn't pick up they just kept calling. Didn't matter if it was 7 in the morning or 10 at night. They are from MSI international running surveys for comcast. They were very pushy and nasty when I told them that I didn't want to take the survey. I have since called comcast. If you are persistant comcast has a privacy option to hide or at least not sell your phone number. I also reported the number to the do not call list.
Just recieved a call from the same phone number; I did not answer and no voicemail was left. I did a reverse phone number look up and found MSI International out of King of Prussia, PA.
a customer satisfaction firm doing surveys for comcast cable. (presumably they do surveys for other companies, too, but they called me on behalf of comcast.)
