Boxoffice out of order

I am experiencing difficulties with my box office account for morecthan a week now. I cannot register my cellphone number to rent a movie. I phoned in to the call centre and they said they will escalate the matter. And still there is no progress. I tried phone and facebook and nobody seems to care about my issue. Why do I have this problem? Dstv just dont care to resolve matters, all they want is money for the subscription and keep on repeating old school movies!!!!
