EXCUSES OF NOT PAYING-OUT A CLAIM

My grandmother passed away a week ago , a very responsible person who paid the clientele life funeral policy every month BUT now they refusing to pay her claim because of the error they did on their side. They wrote T Mnisi instead of J Mnisi even though they have her ID number , correct bank account and address. Clientele life will call you everyday for sales , false advertise but they don not get back to you when its regarding pay-out. At a young age I am at I was thinking of taking a policy with them but now I see what people have been warning me about and it really pains me because my grandmother must be buried this coming Saturday 19.03.2016
