They keep calling me for over half year. Yesterday was maybe their 50th call since then (3 calls yesterday, which I didn't answer, couple of calls last week). This is their second number. First one was from Japan. I myself work in sales, so really was just interesting to listen the way they sell. In the beginning it was fun - try make me buy your stuff, I'll never do. When on 5th call of their sick aggressiveness I told the guy just to stop talking and never call me again and hung up, he called back like 10 times within 3 days. Weird experience. But worth knowing. And yes, it was about investing.. around 10k.
