Hello and welcome. Thank you for providing an opportunity to assist you.
To begin with, I am deeply sorry for the situation that you are facing. Whether this is a case of mis-selling of pension or not is a matter of legal debate.
Though much would depend upon what are the exact facts of your matter, from the primary information that you have narrated in your question, it certainly seems to me the case of mis-selling of pensions. I also believe that at the time of selling, there has been some material concealment of pension facts and supression of some information which has lead you to buy this pension.
However, for this you will have to take help of a local attorney to help you make out a case. However, you can do two things simultaneously.
First, see a local attorney and while giving out exact facts of your matter, explore possibilities of going after the firm / person who mis-sold you the pension.
Secondly, and simultaneously, you can also reach out to Pensions Ombudsman. Their service is free and open to people who have a complaint against those responsible for the running or administration of pension schemes.http://www.pensions-ombudsman.org.uk/
You can also file complaint with them as well.
