This RUDE solicitor called and was pushy about some sort of heater service, asking an elderly man "WELL WHEN DID YOU HAVE IT DONE" and then repeating that to his elderly wife -- PUSHY AND RUDE!! (They actually did have the service done previously). i TRIED to phone back 206-879-4411 and wouldn't you know, it's a FAST busy signal... This thing is just plain balogna, I'd mark this one a scam.
Do not answer calls from those you are not familiar with and I would not be so quick to rely on any potential they might leave. These telemaggoters often use fake messages in the hopes of tricking people.
