Please just terminate the contract

I'm currently unemployed and have been so for 3 to 4 months so it's been a bit difficult for me to continue with the monthly payment on the educational plan I have taken out for my daughter so on the 28/04/2015 I mailed Old Mutual asking them to terminate the contract and refund me what's currently due to me. Two days later I called them and asked how far the process is and only then I was told I need to send them a certified copy of my ID, proof of address and bank statement. I obliged and did so even though it was a costly exercise on my part considering I'm unemployed. Today I receive a mail stating that my request will not be processed due to me not giving them my policy number and me not sending my bank statement. It's amazing that when you take out these policies, they don't ask for certified copies, proof of bank statement and address. I gave them a confirmation letter from the bank with acc details, how is that not sufficient, I gave them my ID number because I don't have a clue what my policy number is, couldn't they ****** look it up??? They want a declaration that the ID belongs to me, it was certified for crying out loud. Please just terminate and pay me back please
