debit order reversal unsuccessful due with invalid reasons

i reversed some Old Mutual debit orders last month as i cancelled all my policies, FNB told me that it will take 40 days to reverse them, then yesterday 07 February i got a message saying that my debit order reversal is unsuccessful because a signed agreement was provided. i have a couple of questions and a request. 1. please send me that signed agreement , 2 does the agreement says i will be having a policy for the rest of my life? 3. who is your client between old mutual and myself, aint you supposed to do what the client wants on his account? you must do what i ask you to do on my account, i am paying you for all the services, including those debit orders you have charged me for reversing them. i want all those debit orders be reversed you have no right to refuse reversing them, its my account i pay whoever i want to pay. please refund my money and if not i will have no option than to close my account with FNB. you cannot be telling me about a signed agreement without reading what the agreement says. and its none of your business you are not party to the agreement at all. as far as i know i opened the policy years back and i have a right to terminate and take policies elsewhere.
