Billing issues

I cancelled my one contract on the 5th of November, I received an sms stating that my sim has been changed to ultra bonus today. However, I was fully billed for this contract on the 1st of December 2020? Why? Please also cancel the get more on this number. I also see my main number is also being billed weird. Its billed as Pinnacle 1GB top up and a promotion 5GB data - where does this come from? I did not not add the Promotion 5GB, I was however billed for it. I don't understand my bill at all. Please correct asap
