SIMCARD AND AIRTIME CANCELLED 7 MONTHS AGO BUT STILL GET BILLED EACH MONTH

I have been struggling to cancel a sim card since 12 July 2024 I have send several emails which I have proof of. I received a email from Mr Price that they will cancel my sim card and airtime which has not yet happened. 7 months later I still get billed R99.00 per month on my Statements for airtime that I do not even receive for the past 7 months. But yet still get billed. I do not even use the Mr Price Sim Card. This morning I send yet another email which Mr Price rep**** that they contacted me regarding the cancellation which has most definately not happened. And was told that they would escalate my cancellation. Why is it so difficult to cancel a simcard and airtime? I have requested this 7 months ago and a few times there after via email. I have the proof of Mr Price email saying this would be cancelled but still receive statements each month for 7 months now being billed for airtime I do not receive a simcard I do not use and requested to be cancelled via email several times. And you just dont get any feedback from them.
