Discovery is a big company with little customer service

Discovery Health has a problem every time with my claims for my son (baby) at Pals Baby Clinic in Alberton. As you know, babies goes for injections from month 1 up until 2 years or something. Pals only accepts cash and gives a receipt to claim from Discovery. If Discovery doesn't have a problem with the codes it has a problem with the patient name. Firstly, the Discovery app, ask for the patient name when submitting a claim with the receipt - so why do they question the patient ??? What is the function for then on the App. I am so sick of fighting with them over my baby's injection accounts. The latest is also an issue with the patient name and now I must resubmit the account. Can someone please sort this out!!!!
