Cancellation of policies

Hello Peter<br> <br> I took out a life policy with old mutual greenlight and later on, found out that in addition to the debit orders I was paying for the greenlight policy (which i authorized), there were also some debit orders going off my account for the Three Old mutual Group scheme policies (which I do not recall authorizing). Since July 2015, I have sent out several emails to Old Mutual asking that these policies be cancelled and that I should be refunded. So far, only one policy was cancelled and refunded ouit of the Three. <br> <br> Please help me cancel the other two policies and get my refund.
