Continue debiting after cancellation

I am extremely frustrated with Vodacom Customer Care, I had a Data contract with Vodacom which started off as R70.33 for cell number ***, I told the consultant initially I wanted to cancel the entire contract, but he convinced me to take a data contract and I was not bound to a contractual period, I agreed. I spoke to Philea who gave me a quotation settlement amount, I was told to pay it at a Vodacom shop as it will reflect instantly. I received the quote and paid on the 30-06-2023 on the same day I received the quote, I immediately after paying, scanned and e-mailed my proof of payment to *** which I received a response e-mail from *** - advising that the cancellation has been loaded and all is in order. My query is - a Debit order of 26 June - R102.19 went off, 30.06.2023 I call for a settlement - R108.29 Quote given paid at vodacom store in Sandton same day, scanned and sent e-mail to confirm cancellation is complete, I got a reply e-mail confirming all is in order, and today I get another debit order R217.37 and not one single consultant can give me an explanation for what it is for, Spethle even said its the last of the last of what? I would like a refund and any other transactions that was logged on this cell number after the 30th June 2023 I am not liable for.
