Absolutely ********** experience

Contract is coming to an end on 05 December 2025. I phoned in on 05 November 2025 to submit my 30 day notice of cancellation once the contract expires. Was assisted by Portia Majola in the Gauteng Retentions Department. She offered me a sim only upgrade and I agreed. She then proceeded to cancel my wife's contract that is far from expiring, leading to early cancellation charges and then also proceeded with the upgrade on my wife's account, leading to early upgrade charges. MTN is now charging me R17000+ in charges because of her incompetence. I need this matter resolved asap,
