Not paying an account and not allowing me to cancel my membership

<p>Ive emailed them many, many times since last month that I want to cancel my membership and no one has gotten back to me.</p> <p> </p> <p>There is a bill they havent paid, and no one will tell me why.</p> <p> </p> <p>I am so fed up and I can't leave. I pay R2500 a month, and I wasnt covered but cant cancel.</p> <p> </p> <p>How is this fair? No one responds to me.</p>
