No claim refund

On the 8th of June I sent through a claim to discovery for refund of specialist payment to me. I never heard anything back from them. So I phoned on the 12th of July and the consultant said they didnt process the claim. I don't understand how that is my problem as it was suppose to be done. And then I phoned back on the 17th July and they said it was put through and will be paid out in 2 business days. I still haven't received payment. So I phoned back today. And the consultant says the claim is now not clear. So I don't understand as I am getting the run around from discovery and I need my claim to be payed! This is almost 2 months now and if they had a problem with it not being clear why did they not inform me! I find this so ridiculous.
