Vodacom contract renewals without proof of recording

Vodacom makes it impossible to get out of contracts or to provide the required feedback/proof of the renewed contract agreement. 24 November 2017 app**** for a 20GB Data SIM card. When I contacted Vodacom in 2020 to cancel the contract I was informed that I cannot cancel the contract for a another year because an upgrade was done by me on 31 May 2019.

I have logged numerous calls and complaints to have Vodacom provide me with proof of the contract renewal however nothing has been done apart from me receiving messages of my calls being closed without any feedback.

I went to Vodacom shop who advised me that it was an online sale, I have requested recordings of the call, however the calls logged by the Vodacom shop was also closed without any feedback.

Friday I phone Vodacom again to log a complaint and received an sms of the issue being investigated. I received a message again a few minutes ago thanking me for my support and advising that the call is being closed.

How is it acceptable that calls and queries raised by clients are blatantly ignored and closed without any proof of the actual resolution of the problem.

Vodacom you are allowing ***** to be committed in your Company and you are *****ing from your customers by keeping them in a contract that is they did approve.
