Vodacom cellphones contract cancellation team needs values

I have requested vodacom consultants to have my Huawei phone contract cancelled since February(monthly request) 2023 as it expired on the 31st of January 2023, nothing was done after calling month after month for cancellation (only cellphone upgrades were given, which I declined) .. until I logged with Tobi in May 2023 notifying me that I am still liable to pay for July as well because I refused to take up another phone offer, so vodacom opted for 60days notice (yet I requested cancellation since February 2023). Vodacom has been billing me unfairly every month even though I specifically requested to have my account cancelled since February 2023. This is ********* and no customer deserves to be treated as such... it's as if I am paying for another bogus phone, forcefully so. When calling the cancellations department on the 8th of July, they told me that they will clear my account yet after 2 hours I received a call from vodacom stating that my account is in arrears, whereas I paid on the app what was due. What manner of sucking money is this? This is disappointing ,cruel and upsetting to the highest level!
