Deductions made and no service delivered

I had a policy with Liberty Life which I cancelled due to poor growth on it. Now for the past 4 years there is monthly deductions for Management fees and some months there are double deductions for this. I am losing money which they apparently invest and claim fees for such but there has been no growth on this policy. No interest added but only deductions made. If I transfer the money to another company it's going to cost me and apparently I cannot withdraw the money due to the amount. What now? I am only losing money and they don't seem to care at all.
