Really poor service

Just want to leave a review for Discovery medical aid. We have been with them before but left due to Covid and now we decided to join them again. I am due to go for a procedure but that is not the problem, the problem is I had to call every single day from the 24th of Feb until yesterday (18 March) to follow up on an authorization number. The service is really poor like 100% poor. Mot only did I get different information everyday from the team, but also none of the information was noted on the system. All they could see was how many times I called in to request information. I have escalated 4 times already as it is URGENT, but no one saw it as urgent at all. Finally my procedure was approved, but something was bugging me to really check this. When I called they told me that actually your procedure was declined due to a waiting period that was added for 12 months. So basically if I went for the procedure on Monday, I would have been left with a huge bill. They should have just said from the start sorry we can't cover you because you didn't list it on the forms when you joined. I was never diagnosed just doctors kept saying change diet and don't stress. Its not because they are not paying but it is the fact that they were stalling so much and couldn't give me the correct information but then you need to pay your money installment. I am still to decide what I want to do and if I want to stay with them, but am afraid the rest are all the same.
