Baby delivery paid from savings instead of maternity benefits

I am so shocked at seen what Discovery has done with me medical claim .on the 9th March I gave birth .I had gotten my authorization for the hospital and delivering midwife from discovery . I paid the midwife cash and sent claims to discovery. Today I see that Discovery now uses my savings to pay for the midwife instead of under the maternity benefit and also pay only R3500 instead of R7500. The part that upsets me the most is that in 2018 gave birth at the same facility using the exact same midwife and it was covered under my maternity benefit.Not only that but the claim for for R7500 and the R6500 which is understandable. This time you take my savings for my normal delivery .Is discovery trying to use up members savings on procedures that they cover under the maternity benefit. This is so wrong wrong wrong
