Because you won’t see the money…
I opened an account with them called them twice to confirm that my account is qualified to the cash back offer and twice I’ve been told I was.

So I put money and did one trade with this offer in mind. I would never else open a position on the DAX with just 25 points stop loss. Because it was more like a bet than a trade I lost which is fine.

I called worldspreads, the company that you always talk with the same person, and asked my cash back. They say no problem but nothing happened. I’ve waited 3 days to call them again and they promised me that it will be sorted on the same day. Nothing happened again. I waited 3 more days and called them today.

And their answer:
Due to the terms and condition you are not qualified to this offer. Good bye.

But I had enough. I wrote a long letter to the FSA the financial authority that should govern these companies and copied the Guardian and the Independent newspapers. And now you know about it too:
Don’t open an account with Worldspreads because there is a good chance you won’t see you money back. And also they have one of the worst platform out there.
