Telkom unable to cancel Recurring data on my contract

I have been trying to cancel the data bundle that I once bought to my contract router. When I bought it I didn't notice it was recurring, and only noticed after a while on my invoice. I don't understand why I am unable to cancel it on my App as I was able to purchase it there. I have been calling the call centre numerous times, I mean it when I say numerous even today the consultants are unable to cancel. I am very upset as to why all the different consultants that I have spoken to have been unable to assist. It seems like even the technicians are unable.

Telkom please tell me your take on this. Who is supposed to help if your team is unable to help.
