While hindsight is an easy vantage point JCLM will be able to ascertain whether- given your investment background, stated requirements and appetite for risk- you were given negligent advice and whether the risks of such schemes were explained to you sufficiently.
It may have been that you were not given sufficient information about the schemes, that they were at odds with your usual investment appetite (which may have been cautious) and you were not told about any additional charges and commissions to be paid to your advisors. Or you may have felt under pressure to agree.
JCLM have experience in dealing with all the above and presenting these complaints for resolution internally, through FOS and the FSCS and- where necessary- through the Courts.
