Received an unsolicited phone call just now on our unpublished land line from 586-574-6012. Picked up the phone and listened...mechanical sound in the background...no one spoke then the caller hung up.
SSI is a survey company, and survey's are exempt under the DNC. Consider getting a call blocking device or phone.. You can google them and many are around $50.00 or so.If its a cell phone, some already have call blocking, if not, there are free apps on the web that will work for some. You can google this. If you have a smart phone, there is a free app called call control. Iphones appear to have apps also. Another one is called Mr. Number.
