NO Policy Contract on Insurance/Maintenance plan

We bought a vehicle with ABSA Vehicle Finance Assistance. About three months after we bought the car, a representative of ABSA called my husband to sell a Insurance/Maintenance Plan to him. We have been paying the R142.50 for 20 months and we do not have an idea what we are paying for. My husband has been in contact with ABSA twice, where they promise him that the policy documents will be posted to us. But to no avail, nothing has reached us ever since. I have got no policy number. Today, I, the wife, married in community of property with Mr Lucas, and signed on the documents at the dealer to get the finance, called and spoke to 10 different people in different departments and could at the end not be helped because I have no power of attorney to get financial detail in this account, as informed by \Abe"a manager. I do not want financial detail"
