Annual Sub Issues

I contacted DSTV last year & requested that they change my billing frequency from monthly to annual. After many attempts(as the agents struggled to understand English) I managed to contact Siyasanga Mbengashe who confirmed that she did the changes(03/12/2015 - ***). As I have trust issues with DSTV(who blames me), I asked for a re-confirmation to which Daniel Tshilombo reconfirmed(04/12/2015 - ***). With 2 confirmation, I was satisfied that changes did take place. Yesterday, out of curiosity I emailed DSTV to tell them I hope I don't get any nasty debit order surprise at this month end. I received a call from Ray Plaatjies. After a lot of beating around the bush from him, it came to light that the changes was not done. Initially Ray tried to test my intelligence by interrupting the email received from Siyasanga incorrectly. I read the email slowly to Ray & pointed to him that my understanding of the English language is better than his. We came to an understanding Siyasanga did not do her job by changing the frequency & **** that she did(not exact words, but come down to this) Daniel also **** by confirming that Siyasanga did the changes. <br> Am so disgusted by the service
