Karen Manning was angry that her policy failed to pay out
BBC Radio 4's Inside Money 2005 was broadcast on Saturday, 23 July at 1204 BST.
The programme was repeated on Monday, 25 July, 2005 at 1502 BST.
Payment protection insurance (PPI) is supposed to provide a safety net for borrowers and help them weather financial storms.
The insurance is meant to cover their monthly loan repayments if they lose their job or cannot work because of ill health.
PPI is big business. Consumers pay more than £5billion in PPI premiums every year.
Most of this goes to high street banks, building societies and other lenders who sell the insurance on the back of loans and mortgages.
But PPI is also controversial. Critics, including consumer groups, MPs and even some within the insurance industry, argue that these policies are expensive and complex and that they may not be suitable for many borrowers.
They say the safety net has disastrously big holes, as many families have found to their cost.
When listener Karen Manning borrowed £5,000 to buy a second hand car, she was also sold a PPI policy which added almost another £1,000 to her debt.
But when, unexpectedly she tried to claim on the policy, she was told that because of her circumstances, her claim would not succeed.
Karen is angry that the insurance policy did not pay out, and angry that it was sold to her in the first place.
How many other borrowers may be paying for insurance they would never be able to use?
Karen decided to join Inside Money Presenter Lesley Curwen to investigate The Protection Racket.
