Vodacom are ********s stay away

Never sign up for a contract with Vodacom. I wanted to cancel due to network issues for weeks and logged multiple requests with Vodacom to fix the issue. They failed to do so. Now when I want to cancel they say I signed up for a 2 year contract however they refuse to send me recording where I gave consent. I was told to go to a Vodacom store when I got there no recording was available. I have been calling nonstop and agents put me on hold and the phone drops. Even wrote emails no response. Vodacom are ****mers and ********s. I have been with them for years now the trust is gone. I’m filing a complaint with NCC no ways.
