Service deteriating / Pathetic

A claim was submitted under wrong ICD codes, doctor re-invoiced with correct codes, we submitted and till date no refund, just one excuse after the other and one reference after the other and no actions. What is happening with the adjustment and not even to mention the scheme. I even had a very upsetting conversation with a Call Centre lady during the week of 20th January, where she actually quite upset me and could not explain to me what she meant by the contract between doctor and medical aid was cancelled. She also told me she also picked up a problem such as we owe Discovery but in actual fact Discovery owes us and will refund soon. Till date absolutely nothing. Why is this lingering on ? Ref. No's:- ***, ***, ***, *** & ***. After speaking to doctor's rooms I found out that the doctor is no longer contracted to medical aid. This forces me to look for a doctor that are contracted to the medical service provider. Unacceptable as certain conditions are to be treated by a certain medical doctor! This is becoming like a government hospital and yet we've been on medical for 26 years!
