After many, many calls from this number, I decided to answer the call. Caller said she was calling from Cancer Centers, they provide supplies for patients all over the US. She was persistent, but I finally got her to understand no. My worry is this number is used for several different groups and the calls won't stop. So annoying.
I am on the do not call list, she hung up on me... report 503-207-0623 to the FCC.gov. There is no Cancer Corporation associated with this phone number on the internet.
Don't answer. I've concluded it is someone who is casing homes, or is mentally ill. Either way, you will make them less harmful by not responding. I've reported this to the real NWCUA. They can pursue this person legally for misrepresentation.
