This call came from a Petco survey

It says it is a company called SSI, Survey Sampling, http://surveysampling.com/ which it gave me this website.  I don't know how they got my number since it is on the do not call list.  I was going to call them back and do a survey of my own...

Says from Utah .   We don't know any one in Utah

That number has been calling us daily at 3 in the afternoon for 7 days. It just clicks ?.. I figured out how to have my phone block the number.

Called me left a message of music playing amd people talking sounded like a party. When I called back it said it was some survey thing..

Called at 7:30 PM.  My mom was in hospice in SLC so this could be related B,S,

Called me during my lunchtime at school, no message was left.

Called the last two nights, once at 9:45 PM and once at 8:30 PM. I would have let it go except we have my Mother-in-law in hospice and my Father-in-Law suffers from dementia and is diabetic, both are very old. I leave to go to work very, very early in the morning and do not need to run to the phone thinking the worse. I don't know who they are except it has something to do with a survey. This should be illegal as I am on the national do not call list.
How can I make them stop?

Don't know what they want, and don't want to know.

It just called me, detroit, mi. May call them back.

this number called 8:30 pm, left no message.
