Bad Service from cancellation department and vodaworld consultants

On the 10th July 2021 I went to vodaworld to cancel my phone contract with them, I was helped by the consultant Magret Baloi. She told me she couldn't help I need to call cancellation department and I did call them in front of her, and on the call I was helped by consultation from retention department and I requested settlement quote and she did send me via email and she confirmed that my number will be converted to prepaid and my account wont be debited month end July since I paid my settlement in full. After few days I called vodacom again to request cancelation letter and they keep on telling me I will receive letter till today nothing. To my surprise on Thursday 12th I received statement and when I called vodacom I was told my contract was not canceled and I still owe them monthly subscription after I paid R2727. 27 to close the account. Today again 16.08.2021 I went to vodaworld again to resolve my frustration and no one knows what happen to my cancellations while I have proof of settlement quotation and the proof of payment I was assisted by Mulalo Motau who told me that I will have to pay for July and August subscription and it will be debited from my account vodacom , Please assist me Thank you in advance.
