Complaint for dissatisfaction of service

I was called in by Noma from Vodacom today and the lady even wrapped the call after I compromised and gave them my ID number, email address ad contact number. The lady called me to advise me that they will be offering me a discount on my contract because I no longer use the Smses they allocate to me for a month and they my premium or installment will be less than what I am paying now, I asked the lady to opt me out of the open plan, she claimed she did but when she had to advise me what would be my installment after opted out of the open plan, she was very unprofessional and there was dead air on the call. I immediately asked a copy of the conversation I had iwth her because now she could not answer me anymore and she already took my details and made me agree on stuff I was not certain about, I am very annoyed and will be taking this to the ombudsman because of the poor service I got from Noma whose working for Vodacom, the request was clear from my end that I do not need the extra airtime after exhausting the one that comes with my contract and that I need a call recording. This is not TCF because she Judy hang the call on my ear and I looked like a fool, this was the same with the Vodacom agent that sold me the contract because I did mention that I do not want any other additional benefits and I specially chose the debit order date to be the 20th of each month upon taking the contract but to my suprise they debited on the 1st of June I think and I did not have suffiecient funds which now affects my credit score due to the arrears I incurred. Now today meanwhile I am typing the complaint another guy called Mhlengi from Vodacom elite something wants to offer this I don't want without addressing the issue I raised with the previous consultant. Can anyone in this platform give me the direct email address to vodacom and vodacom elite CEO together with their complaints mailbox
