Oregon’s Attorney General sent cease and desist letters to six different companies after receiving complaints of unwanted robocalls from Oregon residents who are on the National Do Not Call Registry. The warning letters explained how state and federal laws prohibit certain unsolicited telemarketing calls to people who have subscribed to National DNC registry. Violations can result in hefty civil penalties.

Oregon’s Attorney General sent cease and desist letters to the following companies:

Renewal by Anderson of Portland (Portland, Oregon)

Alleged robocalls involving solar energy, windows, and other home improvement products.

Velocity, LLC (Portland, Oregon) 

Alleged robocalls involving work from home business opportunities.

Be Safe at Home, Inc. (Mattituck, New York) 

Alleged robocalls involving solicitations for medical alert bracelets.

Yelp, Inc. (San Francisco, California) 

Alleged robocalls involving solicitations for ad space on websites.

Tru Blu Pay (Portland, Oregon) 

Alleged robocalls involving solicitations for payment processing tools.

Bloodworks Northwest (Seattle, Washington) 

Alleged robocalls involving solicitations to donate blood.

A spokesperson for Yelp said the company does not engage in robocalling. In an email to KGW, a Yelp spokesperson said she is aware that some people have impersonated Yelp when making solicitations.

The other companies who received cease and desist letters from the Oregon Attorney General's office were either unavailable or did not respond to KGW for comment.
