Bad service and poor attention to detail

I recently submitted two claims to Discovery and I'm absolutely appalled with whomever handles the processing of claims submitted. Both invoices had been clearly marked with the practice numbers and the name of the doctor treating me. To my surprise I received an email saying the claims were rejected because the provider's practice number were not found on the claim. I followed up with their call centre pointing this out to them, and they also seem to be a bit clueless with what's going on because even they could see the information needed. For someone paying so much for premiums I feel deprived of excellent and effective customer service. This level of shoddy service is UNACCEPTABLE especially in a market where cheaper and more effective suppliers can be found! Hire more competent individuals to ensure the work is done properly!
