What started out as a trustworthy and comfortable experience quickly turned into horribleness. It started with a persistent call to invest into Tesla Motors. I being a champion and influenced by another friend to invest in any company doing its bit for environmental protection went into it. That is when the trouble started. I kept getting daily calls from "brokers" telling me to place things without stop losses. Into various other things other than Tesla Motors. Their excuse was to build up more to invest into Tesla. After that the disaster of flight MH17 happened and the markets all went crazy. But they were persistent. They kept trying to wring me out of money even forcing me to call friends to borrow. They were like "TRY!!! TRY!!! TRY!!! JUST ANOTHER USD 1500!!". They sounded angry. Don't know why. I told them it is impolite to speak that and hung up then they called back immediately. They blamed me for just not following them when I had already agreed to their terms. I felt threatened because I had to give some ID info for "verification" as they verified themselves to be legit. In the end I sent a termination email but in the end lost a substantial amount.
