Misleading and ********** sale

first thing first , i really so disappointed in the way all of this unfolded , i requested a quote online and someone called me the name of Cassandra Bruintjies , she called me and explained to me of various plans i can take , i decided to go with the day to day plan as she advice that it covers for ambulance assistance in case of emergency ,she even advised that they use ER24 , to my surprise when i check my policy schedule that was not covered , i requested for the call centre to call me back , the consultant did call me back and advised me according to the schedule , this morning the manager called his name is Kurt , i told him the whole story of what happened and he advised they cant change the wording , i mean i as a client i am mislead , i was sold something **********ly, i didnt make an informed decision since now they telling its not covered, Kurt is explaining to me that it was a misunderstanding from the agent side , like really ??? the call recording is there , can this be taken up to the highest level as i feel that i deserve the cover that i signed up for , please revert to me urgently
