Vodacom Content Services milking me though I did not subscribe

I spend a lot of time unsubscribing from Vodacom Content Services. Yet I keep seeing charges Content Service charges in my monthly itemized invoice. Sometimes I will not be using the phone, but 2 hours later when I pick up the phone, I will see an SMS that I have subscribed to Content Services.

a) Why is that when I never subscribe to Content Services, I spend a lot of time unsubscribing to Content Services? b) Why is it when on 04-12-2020, I check for Content Services, it shows nothing but I still get an SMS that says I am still subscribed to Content Services?? c) Why is it that when I use the Vodacom App to request that my number NEVER EVER gets subscribed to Content Services again, I never get a confirmation SMS? I have made the request many times in the past 7 days but I get no SMS confirmation. However, I get SMSes when I change the Marketing Opt-In status?

Please explain to me why I keep getting billed for Content Services I never subscribed to? Why am I not able to permanently block Content Services Subscription via Vodacom App and not getting confirmation SMS? This is really disappointing!!
