Discovery blatantly going out of their way not to pay claims

I've submitted 2 claims now for my wife's gynecologist appointments for our upcoming baby, both not paid stating either the "date" on the invoice is not clear or procedure is gender specific. The date reflects inline on procedure as 240108 and in the top right of the invoice 8 January 2024. But reason given is date is not clear. Then secondly stating that the claim is not paid due to being a gender specific procedure, my word, one would think that 2 people on the profile, 1 being female surely is the patient that is currently going for routine pregnancy scan check ups. Page 2 of the submitted details contains the patient name for the receipt of the invoice but NO due to the credit card slip covering it on the Invoice itself the claims department can't use commons sense and claims it against the male on the profile. Discovery at this stage literally goes out of their way not to pay claims.
