I'm surprised the ftc hasn't come down on google yet for all these unwanted calls. We receive several pre-recorded message each day from different numbers about google ad placement in our local market.
We keep blocking these numbers but they just call from a different number a week later, this is the number of the week I guess.
This number if called states that they are calling about back taxes owed to the State of Washington. Sounds as though they are using illegal numbers or someone at the state is using state phone numbers to carry on their scam activities.
