twpd - I can sympathise with that - got the runaround my self on an endowment.
Turns out the shyster who sold me the poicy closed and then restarted his business with new names etcetera.
I am still paying an amount into the policy for the same reasons as yourself - wanna keep it going and too much to lose.
Ombudsman said - sorry - company that sold it does not exist - but the company I'm paying too can keep taking the money aaargggh.
BTW - keep on at the ombudsman and keep asking for final final result - because the initial 3 decisions you receive are not actually by an ombudsman but by some office toerag acting on his behalf - and only the OMBUDSMAN has the final say.
Best of luck.
