Dstv contact center agents are no longer caring for the clients

I was affected by the fact that my smart TV will no longer be able to stream DStv Now and I was supposed to get sms containing voucher number for me to purchase a DStv Streamer Decoder.. I've been waiting for 4 weeks now for simple SMS! I wish somebody could call me and tell me if I'll get that voucher or Not.. I've been a loyal client for the past 18 years.. Premium subscriber at that! I tried to call in several times with the same outcome: being sent from pillar to post.. I'm so ****ed
