Vodacom Pathetic, when it comes to cancellations

On 11 May 2020 I called to cancel my contract at Vodacom as at 30 June 2020, the consultant, Chad told me that I should call on the first dat of June, which I did, and then spoke with Endura. I thought everything was in order, as I check that no data was available from 1 July. on 27 July I was debited, and I reversed it, as I have cancelled the contract. On 28 July I spoke with Chad, and he promised that the account will be cancelled and the "arrears" will be fixed. On 17 August I did a follow up with Nobuthle, and it was still not done. Chad promised that it will be done, and then on 19 august I spoke with Laura, and still not done. Today 21 August, I spoke with Precious, Joshua and still no joy. Chad is not coming back to me, by fixing this issue. This is really pathetic!!
