I called back and a recording asked to select:
1. customer representative
2. add my number to their do not call list (NO way I'd leave my number!)
3. leave a voice mail
I entered 1 for a representative in order to determine what call was about, but it timed out to their voicemail
Stupid telemarketer started talking to my home answering machine like a human answered. "Hello, good afternoon. How are you doing today?" Really? Then she hung up. BLOCKED.
