Robo call from level3 communications (issaquah WA ) they state they are the IRS and are filing a lawsuit against you to call them. My husband had a similar call with threats of being arrested in seconds as a policeman was being dispatched about a year ago. This is a scam. We called the local police dept and they stated this arrest threat is bogus and doesn't happen like that and the IRS doesn't make calls.
This is a scam so don't call them!!
