Claims not Paid and Poor Service

I have submitted my claims to Bonitas a month and a half ago already after paying cash, what frustrates me the most is that no one even bothers to get back to you regarding your claims if it is incorrect or there is something missing! How do they expect us to know that? Whenever I follow up there is always something missing and why cant the 1st agent you speak to pick that up? Why do you ALWAYS have to phone 10 times to follow up? I had to phone AGAIN this morning to follow up as i have not heard anything from them yet and once again the same story, this or that is missing!!!!! I now have 4 outstanding claims that are not paid. I'm very disappointed , I really can't wait to change to a better medical aid. Bonitas is really frustrating , I need my money urgently!!!
