5G cancellation process failure

I cancelled my 5G uncapped on 01 Nov 2021. I got a 4g sim as I moved to an area with no 5G coverage. I cancelled both online as per instruction, and telephonically.

To date, this 5g has not been cancelled, despite their many email follow ups. The 4g has been cancelled, even though I requested the cancellation after.

Is your cancellation button for 5g working bafwethu? Please refund me my money for November, and cancel before you end up charging me for December as well.

Request #***2 and Web-CancelSIM ***.
