Discovery's pathetic customer service

I recently submitted a claim to discovery to be reimbursed. They first rejected it and said that duplicate codes were submitted and that's the reason it was rejected. I then pointed out that the invoice indicated the different times were indicated and the consultant promised to contact me after 3 days as she logged an enquiry . This time lapsed and I called again and a different consultant told me that he would log an enquiry into the enquiry that the previous consultant logged and would be contacted within 3 days. <br> Again this time lapsed and I've still had no contact from them.<br> <br> Seems like they prefer you get another service provider as they too busy to respond to you or assist you.
