Everything to stall paying a claim

I recently submitted medical expenses that I had incurred where I had to pay the service provider directly, I took a clear photo of the accounts and submitted via the discovery app, later that evening I get a call to advise that the copies are not clear and that they can only work off a scanned image. The following day I scanned the accounts and submitted by email on Wednesday. On Friday I receive a call from my wife advising that Discovery is trying to get hold of me, well they could not have tried very hard as I have been available on my mobile and my office phone all day and I am the main member so they have my contact details. They now require the procedure codes and the date the procedure took place, since I had to get authorization they would have that information but they would rather stop processing the claim and keep messing the client around a bit longer. Like most corporate structures in RSA, service levels are non existent and the clients are there only as a nuisance factor.
