I just got this call (Live on Whidbey Island) and same situation. Called and they left no voicemail. I called back to hear a recording that said I have reached a non-working number...... Frustrating!!
It's a scam /con DON'T ANSWER THIS NUMBER
Call Type: Someone pretending to sell something and save me money BS
They have called back 3 times as I am writing this warning, Now I have to find out how to block!
