Discovery headache

Everything with discovery is just a headache. My first month with them I had half months cover but we're charged a full month. Before that it was a struggle to get my medical aid activated. They captured my details wrong and just cancelled my application without informing me. I did a claim with them and they just did not respond this was months ago. I emailed again asking about it and no comment. It's like talking to a wall really. And if you phone the call centre you have to wait forever or they drop your call.
