Manager Shouted at me

I phoned in the one day to confirm that I can visit a certain dentist in my Area. The consultant who spoke to me over the phone was unable to answer when I asked him if this dentist was on the INGWE Student plan's network. Thus, I asked him to phone me back when he is able to answer me, which his he answered: " Yes, absolutely" . Anxiously awaiting his call, he never got back to me. I had to make the appointment with my dentist. So I phoned back again. I complained to the next consultant I spoke to and asked to speak to the their manager. Eventually she put me through to the manager after she struggled to get a hold of him. When he answered the phone, I was quite upset, but proceeded to calmly tell him the problems I am experiencing with Momentum. I even mentioned the name of the man, who I spoke to the previous day, name. He was extremely arrogant and rude. He barely gave me a chance to speak to him and immediately interrupted me. He did NOT listen AT ALL! He started shouting at me horribly. He said that they did try to phone me, but he was referring to 2 months before when I also made a query with them, and they phoned me back the next day, and I could not answer as I was in class all day. The fact was that I was speaking to him regarding the most recent matter. I tried telling him and he just kept shouting. I could not believe it at all. It was absolutely HORRIFIC. My sister heard this happening, and was astound. I will definitely be changing my medical aid to DISCOVERY. Even though I am only a student still, I will never ever return to Momentum. This experience was horrible. I will tell everyone I possibly can to absolutely stay FAR FAR AWAY from Momentum. They treat their loyal and paying customers like garbage.
