No assistance whatsoever

i would like to say i am highly dissapointed with the way discovery is handling my issue. I have been trying to load my claims to update my tax certificate and all the response i get is an email with no reply that goes like:"We only received a receipt as proof of submission report. Please include the related account and refax it to ***. Discovery Health. I tried calling to find out the issue but it was clear i submitted invoice statement with my medical details. No one is willing to assist me and i have been submitting the same statements to claim for other days. why is it now different? This is the first time i am struggling with discovery, I have been advocating for discovery my whole life and this by far is the worst experience ever.
