Who called from 8173816535

Called and automated message. Getting a lot of spam/scam calls today

It calls again 2 days later after I blocked from house line, it calls private cell. Recorded message of survey asking what walmart, target other stores I shop at and how often. Survey call. Getting tons of this both phones 6 times a day. Really sick of it. On Do Not Call Registry

Caller ID, "Unavailable",  If their ID is unavailable to me then I am unavailable to them. We just unplug the phone and let them waste their time and we don't have to listen to the ring.

Out of Area call, no message. Not interested in any survey or sales pitch any where in the USA.  I make the decision on that matter.

Sat. May 27, call from this number.  Didn't answer because I didn't know who was calling and they didn't leave a
message.  I began a few years ago not answering these but they keep on with different numbers.  Once even used my number to call and also a local flower shop number.
