Charged for canceled services.

I had a mobile data package with Vodacom and in 2018, when I renewed my phone line, I also stated that I dont want the data package any more and that it should be stopped. 2 months ago, while talking about my contract with a Vodacom sales person, it surfaced that I was still paying for the data package that is unused. I have logged a query with Mondo (Whom it turns out did the upgrade for me), but for more than 2 months I have not heard anything from them.

So I have been charged for 2 years for a package that I wanted canceled. That is nuts and has to be sorted out asap.
