Pricelock debit nightmare

I was sent an ad to entice me to take a 2 year price lock contract on April 26 this year. For 899 per month the package included Premium, Explora functionalities, Showmax and Disney. I decided to take up the offer. It took me an exhausting week of back and forth and endless phone calls at my expense to get the thing done. This was commenced on June 5th. Since then I have had endless difficulties. My Showmax was deactivated and my Disney was cancelled twice. Understand, in years past you could deal with the call centre and a friendly person would easily and efficiently resolve your query. A visit to Home Affairs is more appealling than dealing with dstv's call centre these days. Most frequently call centre agents imply I'm a **** and try to deconstruct and explain my package and justify why things have been cancelled. It's a contract. It's been done. I've been paying since June. It amazes me that staff have carte blanche to argue with customers, have zero understanding about the fundamentals of contract law, and are not informed of the offers that are sent out by your marketing department. Contact with anyone outside the hellscape call centre is hermetic ally sealed off because it seems nobody wants to hear from customers. The service is abysmal, rude, ***********, and chaotic. I'm paying nearly R1k per month and am treated like ****. This week's problem was the dstv debit which was mysteriously increased. I had left just enough money in that account to cover my sub. My bank bounced the debit and charged me a penalty. I have spent hours on the phone to no avail, being told your supervisors 'are busy' which sounds like I'm a pest and I'm somehow less important as a customer. My requests for someone to call me back were declined. I wrote I believe 3 or 4 emails pointing out what had happened, asked for the debit to be cancelled so the bank would refund me and I would then pay by eft. Zero response other than an email exchange from Priscilla who was doing the usual thing of implying I'm a **** and then backtracking when I referred to the attached ad with the offer I had emailed with my query. She hadn't read it initially. I have to say before dealing with my problems I have constant arguments with agents who imply I'm lying about my contract so I literally have a screenshot of the ad with the offer on my phone that I have emailed more times than I can remember to finally get your argumentative staff to stop. I can never directly address a problem because I have the barrage of explanations about Disney or something else that are irrelevant. I have to repeatedly tell them I have a contract, in effect from June, which includes Disney and the terms are not to be varied. It is exhausting, frustrating, infuriating. I would like my debit order cleared up, *as I requested*. The debit for November must be withdrawn first so I can get refunded by the bank, then I can pay you via the app. I see next month they are charging me even more. Who the hell does this? Please adjust my debit to reflect the proper price lock amount I agreed to, and for the love of God let my account reflect accurately what my pricelocked package includes.
