Vodacom has pathetic service!

I contacted Vodacom on the 01/03/2021 to cancel my contract. They sent through the cancellation quotation on the 01/03/2021.

I made the full payment and e-mailed the quotation signed, proof of payment and copy of my ID through to them on the 04/03/2021 to *** / *** / *** / *** and ***

I then sent the same e-mail again to all the above addresses on the 10/03/2021.

I have called the call centre numerous times as well to get this sorted out but they keep saying I have to email the documents through to the same email addresses I have sent it to before. Another time when I contacted the call centre the retentions department said they cannot help me until the payment has reflected and i need to check with the accounts department. They then transfer me and the accounts department says the cannot help me until the retentions department has put the cancellation through. So please tell me how anyone can resolve a problem when it keeps being transfered and avoided!! I am so fed up with Vodacom and their lack of service. I just want this contract cancelled asap !!!!
