Can't get hold of Discovery

Struggling to get hold of Discovery telephonically to follow up on 5 chronic claims they have processed incorrectly. Select chronic option from menu and call drops while holding; request normal claims department transfer you to Chronic and call drops while holding; can't complain on their website as the Captcha link is broken. No response on Whatsapp. The refund needs to happen as a result of a complaint being lodged with the CMS which found in our favour. Discovery have reprocessed the claims and paid to the provider not us. They are delaying reprocessing correctly and refunding us. In addition, they have continued to process and pay the claims incorrectly even after the CMS advised the claims going forward till March of this year need to be paid in full. In March the decision will be reviewed.
