With life cover, if 'waiver of premium' was added, you 'should' have received a report (if you took advice that is) detailing everything. I guess this is your get-out route so if you received this then how would you now reasonably complain. Obviously if you went direct to an insurance company the process might let be so stringent (when compared to what I have to do).
