Beware of promised benefits not being paid

My frustration levels are just over the top now. I have been trying to claim for APPROVED PMB. Benefits that were promised to me and I was told would definitely have to be paid. We have submitted three times now over months and months, and for unexplainable obscure made up reasons, I have still not been paid. I am out over R5000, which I would not have spent had Discovery not agreed to pay it before I went for treatment. Its now the end of the year and whilst my other queries have been resolved, this one has left a very bad taste.
