Incorrect Billing and Info

I received an SMS saying that I can upgrade to DSTV Premium Streaming for R550 per month, I tried the link on the SMS and it was sending me a page where it asked for payment of my current package, I managed to chat to a lady on the 16 Sept 2022 and she said the discount was loaded on my profile, so I need to upgrade on the website, I did and it charged me a prorata for Premium, however now I see am being charged the full subs for Premium for the month of October 2022, I chatted to Noko Thlako and this person says I must use the link to activate it(when I told that it was giving an error) and is asking for proof of chatting with previous person, how does one keep proof of a chat, this person making it seem like I am lying. I wish that people in DSTV could listen or read carefully. Now here's the worst thing Noko says that a ref number will come at the end of the chat, guess what I am still waiting....geez its very frustrating when you in constant communication with *********** individuals. DSTV, please pull out all the history of my chats and calls, do a thorough investigation and sort the billing out before my next billing date on the 5th of October 2022
