Billed for Box office but service never worked!!!

We are being billed very month for Box Office but we've never been able to use the service! Since August 2015 we have been calling the call Centre and we have never been helped! We are kept on the line for hours and they don't even have the decency to call u back if you get cut off! When will this be fixed MultiChoice?! We are still waiting for your technicians to call us back, 3months later! <br> Are we even going to be refunded for billing us on a service we can't use?!<br>
