Angel Broking — Misleading & misbehaving

I'm trying to be as true as possible. These people will call you from a no and tell you to open a demat a/c in their company. Then they will compell you to buy options with Thursday expiry. If your a newbie, they guide you to buy call options/ce and make some profit, but then they guide you to make loss, and then to recover they tend to buy more, which ultimately will make losses as per as my experience. They won my trust 2nd time and did the same thing again. And when you pin them, they get back say, I never said you to buy this, I made you profit, I didn't make you loss.
So please avoid this scam and save your money.
