Double charge for Box Office rental

<p>In December 2016, we rented a movie using Box Office. We made payment, but the title did not become available. We repeated the process using my wife's card, and ended up being billed twice. </p> <p> </p> <p>Subsequently I tried to reach DSTV/Box Office on four occasions using the only option available on their website - an online form. I have not had any response. The billing mistake I can excuse, but the complete lack of follow up is completely unacceptable.</p>
