No feedback ever

I have logged a query with discovery more than 2 weeks ago regarding my self payment gap which increased from 10 000 to 14 000 with no logic answer. I was sent a report making it up and spoke to Anele at the call centre regarding it. There are claims for scheduled medication which are increasing the self payment gap even where the claimed amount is in line with the scheme amount. Anele could not explain and said he would enter a call to get it looked at. I have tried 5 times to follow up on this, I keep getting cut off from Discovery side or just sit on hold forever and then silence and says mailbox is full. Got a told of a call centre agent once on Tuesday who said they would email Anele to contact me and nothing. This is beyond ridiculous now. What do I need to do to get someone to tell me what is happening.
