Collection agency "Dynamic Collectors" or "Chehalis Collection Agency," neither of which have I ever heard of or have any business with.

Fake tax debt collector.  Speaks broken English, at best, tries to claim they are from IRS, working with the Washington State Dept of Revenue (No such thing) and that you (or I in this case) has a bad State Income Tax debt, which, again, isn't possible, as WA State does not have personal withholdings of State Tax...they collect their tax thru Sales and Property taxes, as well as outrageous gas, cigarette, and alcohol taxes.

Comes up as Dynamic Collectors out if Chehalis, WA. The other collectors leave a message....I have a bill or two in collections. These people don't. Thinking someone may be spoofing their number....

Ditto here.  Thanks for the info Ben

Called my cellphone and left a message for a mumbled name that is nowhere close to mine. Blocked.
