Telkom - Prime Video Subscription a ****

I have cancelled my Prime Video account on the 8th of January 2026. I was charged the full amount in January 2026. It's fine, maybe because I cancelled during the Month. Come feb the amount was also included in the February invoice when i cann thy topl be. I was billed in arrears; February would be the last charge. As of today, 02/03/2026, the amount still appears in the March invoice. Every time I call, they can see the subscription is cancelled, but I'm still being charged. The lady today said they will credit me, but it won't appear in march invoice, it will appear in April's invoice.
