Termination of contract without approval

On 27 November 2021 I app**** for a black Friday deal online of 400Gb Sim only deal with Vodacom. I received and email confirming that my application had been approved and that the courier was on the way. On the 2nd of December 2021 my sim had not been delivered and I decided to chat with Vodacom via Twitter Dm,I told them my story and I was told the application had been terminated because I was unavailable for four days to confirm my application.

I requested a call back so that I can get clear understanding as to what happened and I am still waiting.What I find weird is no one called,if I was unavailable they had my email to use.

I have never been so disappointed and inconvenienced at the same time because I have terminated my existing contract with my current service provider.
