Either poor administration or stalling tactics to pay bills ?

Submitted a doctors account and cholesterol test for my husband on 10 Januarie, followed up two weeks later and I was told the bills were declined because the person is not on the medical aid, they admitted was an error and they will resubmit. Two weeks later some of the doctors bill finally gets paid but not the Pathcare bill. I called again and was told that they did not capture the second bill on the email and again will resubmit. weeks later I get a cryptic email that the bill (PATHCARE) bill does not have sufficient information, I reply to the email of 20.2 to ask what is outstanding and did not get a reply. I called today and I was told the bill is not clear, they need a clear copy scanned, they are also not willing to get that from Patchcare , as my copy will scan the same way. So NOW I am convinced that the company policy is to stall paying claims.
