Credit Insurance cover

I opened a storecard and a credit card some years ago with Woolworths and took out credit insurance on both which I paid monthly. Last year in December I was retrenched and went into the store to complete all the necessary documents in order for the credit insurance to kick-in to pay the installments. All was good and it paid both for 6 months. In the meantime I tried to find a job but with no success. In July Woolworths Financial Services contacted me and I explained my situation. They requested bank statements as proof that I am not earning an income in order to reinstate the credit insurance. I provided them with the information immediately as well as in September when they again contacted me. The past 2 weeks I have been harassed multiple times a day by Blake and Associates as Woolworths has not handed me over for my credit card which is in arrears. The funny part of it all is that my store card is up to date, they reinstated the credit insurance on that. The expectancy is now that I must make arrangements with Blake and Associates to pay the credit card whilst I have credit insurance which I stipulated in my contract and signed for.
