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!!
Called once. Didn't leave a message. I have had my phone number for about 9 months and only very few people have it. I do not know how they got my number. They are a waste of air.
Called me twice today, both times I missed the call and they never left a voicemail. I've tried to call back multiple times and the call "cannot be completed as dialed" or "all circuits are busy". The number should be completed because that's the number they called from. And all circuits are busy on one of the biggest networks on a beautiful sunny day? Doubtful.
