It has been brought to the light that Natwest sold PPI wrongly to its customers. PPI was added to the credits and loans of the customers in several ways. In some policies the check box for PPI was already checked giving no choice to the borrower. In other cases, it was added to the policies without telling the customers. Another scenario is that it was sold to the self employed people. If any of these scenarios match with your policy then you can consider filing the claim.
