Discovery says die and look for network hospital

I had an emergency which needed me to be hospitalised immediately, I went to Waterfall Hosp and got treatment. I had to go under an MRI scan which they paid and they are unfortunately refusing to pay for my hospital admission on the reason that I was supposed to use a hospital in their network when the was an emergency. I have queried and the asked me to get motivations which I did and they are still declining my claim. Seriously speaking I am wondering when one is at a stage of life or death do you have the luxury to look for a hospital to get treated. if there are any medical aids with better offerings please do contact me I m on my way out of discovery immediately
