UNSATISFACTORY SERVICE RECEIVED FROM VODACOM

I had taken out a Contract with Vodacom which expires 10th of August 2024. I had originally sent Vodacom an e-mail during June 2024 advising of my cancellation of my contract and as usual no reply. I had again on 1, 16 and July 2024 again sent an e-mail for cancellation only an acknowledgment with reference number. I also advised Vodacom on 1 July 2024 that I had received a call from a Consultant advising that they offer more data for less amount which in the e-mail I advised that I am not accepting it. Despite all my e-mails they sent me Contract to sign on 1 August 2024 which I have not signed and I e-mailed the Contract which I drew parallel line across and stated not accepted. Despite e-mailing I receive an account which I dispute because there is a number that they are charging R79.99 every month which does not exists. I have not even received a new handset and on what basis are they charging me I HAVE NOT SIGNED THE CONTRACT WHICH WAS E-MAILED. On what basis are they billing me. Vodacom is quick to sent the bills but does not have the courtesy of even calling me or responding to my e-mails. I also received the sms of call regarding my cancellation of the Contract.
