We are senior citizens and we are receiving calls from this number all day long and after 9 p.m. at night!!!

Random call - no answer when I picked up the phone

Numerous calls all hours of the day/night with no answer!!

This number has called me 6 times today and never leaves a message

GOT THEIR NUMBER I HAVE A BLOCKING # ON MY PHONE AND HEN THEY CALL MY PHONE DO NOT RING . SO LONG AND BON VOYAGE  TRY AND FIND A DECENT JOB LIKE OTHER PEOPLE OF COURSE THAT IS DIFFICULT IF YOUR NOT A CITIZEN OF THE GREAT UNITED STATES OF AMERICA.

I get calls from this number numerous times and there is just silence when I say hello. MAKE THEM STOP CALLING PEOPLE ON THE 'DO NOT CALL LIST"!!!!!!!

I have received so many calls from this number, and the 7030 one as well. So many, I can't even count. I finally decided to answer today...said hello, and there was complete silence, from both numbers. I looked up both numbers through the White Pages reverse phone look-up. One came up as a MEDIUM risk spam alert and the other came back as HIGH risk spam alert. I am no longer answering the calls. Even though I get silence. Want to find a way to keep them from calling my home. But with no one responding when I say hello, I don't know how to remove myself from their list. It's after 9pm here where I live, and I just received another call. Darned spammers!

They have several numbers they use. I just answered this call..I am sick of these jerks calling me all hours. I got 6 calls just today from these idiots!! The guy said he was from SSI, now I know it's not Social Security Insurance...LOL. They denied my husband years ago. So I assume it has to do with Surveys.
He went on the ask if there were any "registered voters" living in the home.
Here's what I exactly told him....
My husband and I don't vote anymore, haven't voted in 15 years...reason being...I don't vote for criminals.
He told me to have a nice evening and hung up...ended that call quick enough...LOL
But incase your wondering...these are all the numbers these survey idiots are using...
(385) 207-7039 (385) 207-7030 and (385) 207-7035...from Utah.

It sounded like the caller said she was with CNN and wanted to conduct a survey regarding telephone usage.
I asked her to add me to her do not call list.  She said they are not selling anything and would like my help with a survey.  I asked if they maintain a do not call list.  She said yes, and again I asked to be added to it, and she agreed.
