Misled and ****** client

In 2020 I was sold a policy by The Unlimited agent. The policy has multiple benefits, one of the beefits its a hospital plan. I was told that I will be paid R2000 per day on admission.

This year in April I got an accident, l was addmitted for 4 days. I put up a claim. When the claim was paid they short paid me , l queried and I was told that they paid less because I was supposed to be addmitted only for 2 days. How am I supposed to know how long I should stay in hospital as im not a doctor? It is the doctor's decision on how long to keep me in hospital. I am unhappy with their treatment, l feel like I was misled and ******. I want The Unlimited to pay me as per their promise.
