The agent that sold the package to me told me that the policy pays for it self, but the products that give money give are not necessarily products everyone use in their household. Unfortunately I took this policy because of the fact that would pay itself and only find out it is not truth and therefore I would like to cancel this policy because is an unnecessary expense for me.
