Dissatisfied with customer service

I called on the 19th of October, informing them to change my payment date. The consultant confirmed that it has been changed and I will start paying on the agreed date as of November 2019. To my suprise I received, an sms that my Dstv has been disconnected. I then made a phone call had to wait for 20 mins to talk to a consultant. I finally got hold of one her name is Sthokozo Mbutho, she was very rude and did not try to assist me with the problem that I had. Her attitude was very bad. She is not customer orianted. She had no solutions for my problem. I asked to speak to her senior, she said that senior is not available. When I asked for the seniors assistant she said it was her. Shockingly she was still unable to assist me and confidently said that my problem cannot be resolved. I am very disappointed and dissatisfied with the service I currently received
