Contract cancellation X2

I contacted Vodacom to cancel both my contracts, a Retentions consultant tried to convince me to stay on 9 September 2022 @ 10.32am (listen to call recording). I gave him the current offer Telkom had given me and its available on the website, i asked for it in black and white before accepting as consultants make empty promises and cannot uphold it. He did the telephonic recording for the contract. To date i have not heard from him and he scheduled a call back the next day 10 September 2022. On Monday, 12 September 2022 the scheduled call back was cancelled. Is this the pathetic service you give a loyal client of many years. i called this morning 26 September at 11.10am and spoke to another consultant who advised the agent i dealt with will call me back shortly as he is at work. To date i have heard nothing from him, to retain me it's easy to offer an upgrade and make empty promises but when it comes to giving the real deal there is a delay!!!!!! I have the name, date and time of the consultants i spoke to.
