membership terminated and still billed!!

<p>My membership for fedhealth was terminated on 30/06/2016</p> <p>I was debited in the 2nd of July for R3639 , which is the amount on my monthly premium</p> <p>I called them and they claim this amount was for June as they debit a month in advance.</p> <p> </p> <p><br />They failed to provide in scheme rules where is says this </p> <p>Is this general practice for a medical aid scheme to do this?</p> <p>It seems unfair as i don`t receive benefits at all and pay a large amount for no service</p> <p> </p> <p><br />I feel i have ****** and they unduly benefited from my termination </p>
