Waiting for fibre cancelation email for almost 3 weeks now

I called Vodacom plenty of times requesting for a reconnection of my fibre network to where i have recently moved to. They checked connectivity and told me there is no fibre in the complex i have moved to. I then requested for a contract cancellation, the lady who assisted me said an email of cancelation will be sent to me, that was on the 23rd of December 2022, today i am still waiting for that email. When i was signing up your sales people were very quick to assist me, when i want to cancel now suddenly i have to wait for hours on the line, i am never coming back to vodacom again and i doubt anyone in my family will be using it as i have received and continue to receive bad experience! The lady who assisted me last is Lerato Makwatle on the 23rd of December 2022.
