Unauthorised add ons

I received a message at the beginning of the month from DSTV welcoming me to Disney Plus. I called the call centre and asked them who requested that service because I did not. The consultant told me it was a 3 months free trial service so I can experience Disney Plus and I will then decide if I want to continue or cancel at the end of that 3 months. Today I get a statement with the Disney Plus included on the bill. I called the call centre and the consultant I spoke to said she doesn't know anything about a free 3 months trial. She told me that there may have been a misunderstanding between me and the last consultant or the last consultant made a mistake. I told her to go and find the recording because I remember exactly what was said during that call. While I was talking the line cut off. I called again and spoke to the same consultant. This time I asked to speak to someone who can actually assist me, she told me all her superiors were in a meeting. She then kept me on hold for minutes until I hung up. DSTV your customer service is appalling. Stop adding services to our accounts that we did not ask for and then charge us for them, its *********!
