Momentum refusing to pay hospital bills

If there was something less than 1 I’d give them because that’s what they deserve. Momentum is totally refusing to pay hospital claims for no good reason. I am now taken to credit Bereu by hospital because of them. It’s claims dating back from July now we are heading to December but these guys find any stupid reason to not pay. They want any kind of information and all was given to them but still they refuse. Now it makes sense why most GPs don’t want to take momentum it’s because of this. When you have a chance run with all your feet when you hear or see a name “momentum” Anyone with idea as to where to report medical aid?
