Endowment Shortfall Compensation?

[JustFairPlay]

Fellow SME's

I have a brief question on the above, perhaps some ground details first ;-
Mortgage with Woolwich 30k taken out in 1988, Endowment to cover repayment via NU(Now Barclays) of IO mortgage over 25 years, mature 2013.

Barclays have made an offer as missold, this is a paultry offer, beggars can't be choosers I know, compared to the even low end of expectations. Have spoken to FSA and Ombudsman to agreed with methods used to calculate which I understand. The Ombudsman said if it came past their desk their desk they would pass it back as OK as correct method of calcuation had been used. It appears that these institutions wanted us to accept the risk all along but now they have been found to have missold the policy they can duck out via their friends and pay a paultry amount and walk away. We the punter are once again left with a huge hole.

My main question is, because it is useless anyone going to the ombudsman, there any redrees I can make on this or am I stuck between a rock and a hard place.

Thanks in advance
