clientele hospital cashback plan

I had severe pains and went to the emergency unit to consult with a doctor. i was admitted for kidney stones yet other needed to be done to establish if it was kidney stones or some other infection. i was admitted for 4 days and submitted all the necessary paper work to clientele to claim on my hospital cash back plan. i was called today the 4 of April 2019 to say that the claim will not be honoured due to being admitted for kidney stones and i didnt have kidney stones but some other infection. i did not admit myself neither didbi study medcine or am i a doctor. this cannot be a fault of mine as the symtoms aphered to be kidney stones. i think this is totally unfair and the claim should be honoured. i have been with clientele for almost 10 years and this sure has left a sour taste in my mouth. i hooe this issue is dealt with and honoured.
