We ignore surveys, let the phone go to voice recorder, delete if sales/scam call, make sure our numbers are up to date with the Do Not Call registry, delete and block scamming intrusive emails, block all sales calls on our cells with the free ATT app.....it has reduce a lot of nuisance people....but some still get through. I thought Washington was going to do something about this. All of the phone providers are not interest, since somewhere along the way, they make money.
