Charged extra!

Good day, I am extremely dissatisfied with the service i have received from DSTV. On 31 July 2020 i was charged a cancellation fee of R180 without my authorisation. For context, i enquired about cancelling my dstv given that i am away from home due to lock down and no one is utilising the package. i chatted to a person on the web chat and they told me about the cancellation, i never authorised for this to be processed. Now i see an amount of R1174 goes of my account, this is made up of 919 for the premium subscription and the R180 for the cancellation plus other fees. firstly no one confirmed any cancellation with me, secondly the contact centre told me there is nothing they can do now because they need to retrieve the chat history first and find out what was really said and then get back to me. this is after i attempted to query the debit order amount via the chat service this morning. I am extremely dissappointed at the service, how can cancellation be done without my permission and also this was just a fee to cancel the price lock contract not even the package. Extremely dissatisfied with the response, the service and the level of integrity that has now resulted in me paying extra for dstv!
