Poor poor Service on Account & Billing

My contract was supposed to be cancelled in October 2017.

I was told to fill in a form to assist with the cancellation - which I did in September 2017. To this day, February 2018, my account is being debited !

Whenever I call the center, they say that they are escalating the matter. It can’t be that it takes 5 months to be assisted. This is ridiculous!

Please can someone advise me on how to proceed with this matter, as I have been reversing the transactions with my bank, but I can’t keep on doing this.

Please help. L Mkhwa****
