Great Eastern GreatLink FlexiPlan and Riders

Hi I have this Great Eastern GreatLink Flexi Plan with two riders of Living Assurance Benefit II and Paycare Rider 65 that was bought a long time ago. However, I cannot remember the features of this plan and the two riders. I also cannot find the documents or any information online. Does anyone know what are this plan and the two riders about? This is because the monthly premium is quite high and am considering whether to cancel any of the riders or plan.
