How do you establish whether you have a claim?
If the risks turn out to be far higher than you would have accepted had you understood what you were getting into then you have good grounds for complaint. If the firm didn't explain in simple terms how much you could lose you also have a good case.

If you are unsure you should consider an complaint, the firm will have to investigate and give you its findings which sometimes results in their agreeing that you have received unsuitable advice. If they refute the complaint you can take it to the Financial Ombudsman Service (FOS).
