Cascade Financial interview questions

Recruiter called and left a message, I called her back less than an hour later and left her a message that I would call again since I got her voicemail. Called back a couple hours later and left another message because I reached her voicemail again. She called back around 6pm and left a message saying to only call once (very rude) since I called as she asked and she was never available. Got an e mail a couple days later saying the position was filled. Why didn't she contact me through e mail if she's never available by phone.
