Discovery Health looking for reasons not to pay after sending authorization numbers.

We have the key care plus plan with discovery and after getting our authorization number and everything was in order according to Discovery now they tell us that they are not planning to pay any of the scans that I have done. They have a lot of stories about the forms that have been filled in by our GP and not a specialist. They should have seen that my GP have filled in the forms and not a specialist and they still have send a authorization number.

THE SERVICE WITH DISCOVERY IS VERY POOR!!!!!
