Not sure who this was, caller ID showed "Innovative Serv".
They called 3 times in less than 4 minutes.
But since I had blocked the entire 606 area code the phone did not ring.

There are a number of companies that start with the name Innovative Services, some in the region, but they have completely different phone numbers and none used the 606 area code.
And since 606 is a Kentucky area code they would have no business in Washington state.
So, I would assume this is just another scammer.
