Slow service from Chronic

My neurologist has sent a request for chronic medication but to date I have not heard anything from Discovery. I have emailed and no response. I see that Discovery Health is also going to stop the email address. The options they have for correspondence via the website and the WhatsApp link is basic. You don't have a space to write a complaint in these and the system generated answers don't always answer what you asked. People don't always want to call they want to send an email.
