Extremely bad client service by Vodacom agents and their team leaders

On the 26th of July I was trying to pay my vodacom account via the Vodacom App. I made the first payment and the App gave me an error so I repeated it. When I went to my Nedbank App to check my balance I noticed both payments went through so I contacted vodacom to log a dispute. They informed me that they will escalate my query and I will be refunded on Wednesday (29.07.2020). On Monday (27.07.2020) Vodacom made another deduction on my account. I contacted them again to inform them that they made another deduction of which they informed me that the invoice was already issued and the deduction couldn't be stopped cause it was already processed. I made a reversal of that debit on my nedbank account and waited for them to get back to me with feedback on my dispute. On the 30th I called them again because I noticed on my vodacom app that my query was closed and the status was resolved. When I asked them how can an incident be resolved without them transferring my funds back or them giving me a feedback they could not answer me , and said I was sent an sms where I was asked to email my proof of payment of which I never received that SMS from them. I sent the Proof of payment to 2 different email addresses which were provided to me by an agent (*** and ***). I then waited again with no feedback from vodacom. I called them again on the 04th I called vodacom again and kept waiting on the line to be transferred to the collections department but they kept on cutting my call until I gave up. I called again on the 05th and asked to speak to a team leader and I was informed the team leader will call me after 2 hours and so I waited. When I went into my vodacom App I noted another new query with a different reference number was opened. I called vodacom again after 3 hours and asked to speak to a team leader of which I got transferred to Ismahil Makgeta who assured me that they will refund not later than Monday (10.08.2020) and I also informed him that I do not want the installment for August to be deducted from that amount I want them to deduct the normal installment on the 26th and also I told him that I saw on my statement that the invoice fee has been charged twice for July. Ismahil assured me that they will rectify that and refund my full amount no later than Monday. I still have not yet received my money from vodacom and I am so annoyed because if I did not make a payment they would be on my case 24/7 . I'm so irritated by this bad service and can't wait to finish my contract with vodacom and look for a different service provider. This is poor client service on an extremely high level. Worse part is that this morning I sent Ismahil an email to ask for feedback he never bothered to answer me. This is unacceptable.
