TELKOM USES PRIME VIDEO AS ANOTHER INCOME

I have requested Telkom to cancel my PRIME VIDEO subscriptions as well as any automatic reactivation subscription. I did not apply for above-mentioned, I did not activate it, I am not interested in it, I don't watch it, but Telkom keep on billing me. Amazon Prime Video confirmed that I have no activation with them e.g. no devices connected, but TELKOM keep on billing me. I have asked Telkom several times to cancel it, but they don't. It is really frustrating.
