I see on their webside that they are regulated by the FSA. You can send a complaint to them. It is their duty to help you when you are scammed.
It is known that some brokers don`t like newstrading and shut down accounts of newstraders. But to cancel trades a long time back is very unfair.
Below a letter I received from the FSA after asking them about trade cancellations. Maybe it helps you:
"Thank you for your email sent on 19 April 2012. I understand that you have a trading account with a firm authorised by the Financial Services Authority (FSA) and would like to know what rules there are that cover the cancellation of trades.
I would like to thank you for taking the time to contact us about this issue and I appreciate why you would like the FSA to comment. I thought it would be of use if I clarify the role of the FSA and comment on the conduct rules for investment business.
I would like to clarify that we are the UK's financial regulator set up by the government to regulate financial services and protect your rights. This means we set standards that financial services firms have to meet and we take action if they don't. For further information on our role, especially in relation to investment business, please see the attached link to our website:
Saving and investments
Turning to our rules I have attached a link to chapter 11 of our Conduct of Business Sourcebook (COBS) which discusses dealing and managing:
FSA Handbook - Full Handbook
If you feel that you have a complaint against the firm then you may wish to follow the steps outlined in the attached consumer guide "Making a complaint:"
