Mtn Contract Department ********

I've written a complaint about this company even today I haven't received my reply. Mtn contract department I'm writing this for the last time ******** why my contract it is still active when I have canceled the contract last year November 2021. After I was made aware in February 2022 I have to pay R392 because the contract was still active even when I called now December 2022 the consultant said I owe R730 for the same contract which I have canceled last year. For the last time I will open a case regarding this issue
