Poor service and solution for problem with MTN Superflex subscription

I was subscribed for the MTN Superflex 10Gig Plan for some time. I unfortunately had to change my banking details about 3 months ago. For unknown reasons the subscription fee was not automatically deducted. On 3 September 2026 I noted that my Superflex subscription no longer existed. I tried paying the subscription fee manually but now where on the MTN App I was able to do that. I reloaded my credit card details and I noted that R329 was deducted from my account I have been trying to talk to someone at MTN Customer Care but I remain confined to a robot trying to assist. My conversations are escalated to an agent but they keep saying they will refer the case to another department. I was also said to send emails to customer care and to the social media division. I was requested yesterday what my tel number is which I provided. My Superflex 10 GIG has not been made active as yet and it is now more than a week. I keep need to buy airtime to phone despite me having paid my subscription fee. I find it utterly frustrating that one cannot talk to someone that can actually assist. I have paid for something and the service is not provided.
