Unprofessional Mbali and dstv TL's /management

Good evening. I called dstv inquiring about why my service was suspended. I spoke to a person wont even refer to her as a lady. Her name is Mbali. I asked her to switch from Zulu to English because maybe there is a communication breakdown. She continued in Zulu. So we had a dialog still in Zulu. She had to nerve to say I started speaking in Zulu and I told I have to right to ask her to switch languages. She told me straight that she will not change. I lost it. Gave her a piece of my mind and I demanded to speak to someone else. She put the phone on the side and later played music.. The call was about 26min. I called again asked to speak with the team leader or manager they were all in a meeting. I insisted. I was on hold for 15min. My query is not resolved. I don't mind paying I just need the breakdown as my last payment was o. The 23 or 24th of December. I wasted time and my airtime due to these *********** people.
