If you are looking to switch your policy from the current insurer to another OSHC insurer, first you would need to purchase a policy with the new insurer and then cancel your current OSHC policy with your current insurer.
In terms of how much you would receive a refund from your current insurer, typically you should receive a pro-rata refund of your premium for the days you wish to switch to another provider.
Depending on the terms of your policy, you may incur a fee for cancelling your insurance. When transferring to a new OSHC insurer, any periods of membership served with one OSHC insurer will count toward waiting periods with your new OSHC insurer, providing there is no lapse in membership.
