DSTV service

At 16h54 I called dstv call center and the call was answered by a lady African lady I can't remember her name, at first I felt as if I was assisted by her but later realized she was making fun of me with her colleagues, they were laughing at me, so I called because my extra view has not been working for a month now and I paid for it last month and last month I called about the same issue that my extra view is not working only the main is working and they couldn't assist me they told me my decoder is old I need to get a new one, so I left it as it is but they kept the main one playing even though the decoder is older than my extra view decoder, the extra view decoder was always on orange the light but today it went green and when I tried to switch it on it was 100 channel that was playing that's when I called the call center to ask them to activate my channels, the call center lady firstly did not know the decoder TV by heart what's on the remote she kept on asking me what's on my remote because she doesn't know how to help me and while she's saying that she was laughing with her colleagues and I kept on saying hello, hello are you there and she responded by saying ma'am your decoder is old you need to take it to dstv center to be checked on my side everything is fine it's your decoder, when I asked her why am I being billed for an old thing that's not playing and they are aware of that she said because you didn't cancel it I then told her to cancel my extra view and send me the cancelation email and she said she can't send the email she will cancel it but cannot send an email as I was busy arguing with her about the cancelation email she hung up on me a d the call took 19 minutes, 19 minutes of my airtime only to be laughed at and make fun of without any assistance. DSTV service is the worst.
