FNB Funeral Plan Agent the worst

I am infuriated ! I phoned on now to follow up on a funeral claim, I was sent a document where my name and date of birth was confirmed as the beneficiary of the policy. Now to be told I am not? Just by trying to find out why, and who changed it, and to whom it has been changed has become an issue with the agents passing me on to every tom **** and harry?

I am very upset, as if this is the case I want to know who changed it and why was it changed? And what authority do they have to change it? But with just a simple phone call that could not even be solved
