Telkom and their VrticalService Provider partnership are so useless

I have opted for a billing of R 199 per month for 80g + 80g in January 2024 and my billing is R 2 490 in May 2024, after calling on several occasions with no success I finally got to know that I must have clicked on a subscription button on their website and it's R 500 pm extra that I am billed paid to telkom by the way then Telkom pays this third party which non of the call center has no knowledge of. They don't even know what the subscription is for but it's on their website. I finally discovered that am subscribed to a company called Vertical Service Provider which I have never heard but the funds for this company is being collected by telkom. This Vertical Service Provider has no contact number and Telkom won't share any details about this company
