I've answered and it says, To hear this call in English, press 1. I've pressed one and it thanks me for calling and said please hold for the next available person. That's when I hang up.
They have called several times, but since I don't answer, I don't know who they are or what they want. They do not leave a message and you get nothing if you call back.
I'm even on the Do not Call registry.
What's the point, though, if companies like this do not get shut down for violating it?
Very frustrating.
