Vodacom! Focus and get your story straight and stop harassing me

Good afternoon... Please can someone please kindly assist me with this problem that I am facing with Vodacom. On 15 February 2023 I called Vodacom call center asking for assistance with a settlement and cancelation of my contract which WAS NOT ON ARREARS. The consulted arranged a debit order which ran on the 16th of February 2023 and over the phone we agreed that he must cancel the contract because they also charged me for penalties. 5 months later I'm in arrears Vodacom what hell Do you want from me, I have emailed the proof of payment numerous times but when they call me they tell that the settlement doesn't matter because on their system it shows I'm Owing them. Vodacom are you taking advantage of government workers or are you oppressing the poor... What's your problem kanti
