Vodacom not closing off account that was settled

About 2 months ago I settled my Vodacom account and paid a pre settlement amount. I even received an email confirming my account was converted to a prepaid.

For some reason I still keeping getting a call for settlement on a previous amount (even though the agent did not inform me previous amounts would not be included as part of the settlement).

I am really annoyed to see Vodacom has listed my account on ITC without even informing me of this.

This is what Vodacom has become, lack of proper customer service while looting on people's money with no value.

I require a senior person in collections to contact me and have the record removed. Failure to do so will result in me putting a post on social media to make people aware of what Vodacom does despite having accounts being settled.
