DSTV doesn't care about their customers - poor customer experience

I can't stream for 7 days from a SmartTV which is 3 weeks old. I have 1 device connected and you guys are populating a message on my TV to sign off concurrent connections. Are you going to refund a week's worth of subscription for the time I'm not able to watch Live TV via streaming? I spoke to your agent Linda via whatsapp, was promised someone would call Friday afternoon or Saturday the latest. DSTV obviously doesn't give a damn about premium customers! Please get this problem resolved asap or I'm canceling my subscription!! I have called DSTV this evening, still no help received.
