I don't pick up calls from numbers that I do not recognize.
But I'm being called repeatedly from this number and my voice mail box is flooded with messages asking me to call back to this number regarding some case file.
Also 3 calls, although two were from this number and another from 425-278-6073. Same IRS suing me message each time. I'm a lawyer so I'm pretty sure the IRS would use different means to inform me of a lawsuit, in addition to the fact that I can't imagine a lawsuit would be filed prior to some sort of investigation/audit. Made a call to the accountant in case.
