Discovery quick to claim but won't pay out whats due as usual.

Worse than pathetic service! On 22 November I went to a Dischem nurse and video called a MD, per discoverys instructions. The nurse put the claim through and it threw out an "IT error" pls ask client to pay and claim back, which on 01 Dec I did, I recieved a ""it will take 3 days to process" I then received a 1 line email saying cannot assist invoice not recieved more than a week later, when I called discovery to say it is in the very same email they confirmed and said sorry they will resubmit, another "3 days to process email" I then recieve yet another 1 line "cannot assist no invoice mail" I then call again holding and spending my airtime because gd forbid discovery picks up a phone and calls the client, and again they confirm everything apologize and resubmit "another 1 line cannot assist" a week later, it is now 22 December and noone helps to have my claim paid back, forget the fact that the very same day I first submit you send me a claim for something you paid dischem in error and insist I pay immediately which I did! Today when I call the lady says " the invoice practice numbers are not clear, pls call dischem and call us back with the numbers, which I do again.... when I call back I get told "we can't help you the service provider needs to resubmit a clearer form" and they won't take it telephonically as per the last person I spent 30mins holding for, Per dischem you are supposed to call health force per your invoicing dept. Then ontop of all of that I have a extremely arrogant manager repeating the same thing to me over and over as if I'm stupid!!! Not only have I now spent hundreds in Rands calling u at least 10 times just to have a R350 claim paid out but I have never had such bad service in my life, I despise calling Discovery, you are so quick to take money but the second u have to pay something out it is ALWAYS problem after problem, you should be disgusted! Really considering changing my, my husband's, my parents and my offices medical schemes.
