Elite mobile is debiting me an upgrade fee every month despite sending a formal complaint.

I was contacted by Elite mobile to upgrade my Vodacom contract. I agreed to upgrade 2 contracts. I agreed to the upgrade fee of R179. 1. I only received Elite mobile continue to deduct the upgrade fee of R179 from my account every month.

Despite sending a complaint, they have not refunded me and still continues to debit my account monthly.
