Discovery Health incompetence

<p>On 25 February 2017 I had blood test done via Mauff AC and partners for R1479.70. Discovery paid the full amount as I had ample funds in my medical savings account. On 7 June 2017 I received an email saying that they paid the amount from the wrong benefit and have reversed the payment. I am now liable for the full amount because my medical savings account is now in the self payment gap. I fail to understand how a mistake on Discovery's side now became my problem. When the claim was submitted in February I had more than enough funds in my medical savings account. Now Discovery just makes it my problem.</p>
