Same here, really annoying.

I called back to see what it is: a women picked it up after some automated music is played. She was trying to sell a five years warranty for a car. I replied with "I don't have a car" and she said if I want to speak to "Natasha"....

I said it's okay and please don't call anymore, and she just hang up on me without saying anything.

One more number for the blocked list...
