Changed from hd to Explora, now Dstv not working

Phoned service centre to deactivate my caravan Hd Pvr and reactivate my Explora. End result is I now have no tv. Service centre claim it's a system error and it has been escalated the the technical dept. and would be sorted out in two hours. This happened yesterday 2 November 2015 and still have no tv. Phoning in again results in the same outcome. No one in authority at Dstv cares and can't be contacted. What a useless organisation of ***********s. My Dstv call centre reference number is ***-i49
