Failure to do cancelation of contract

On the 12/03/2021 I called vodacom cancelation department to have my contract canceled since it was coming to and end on the very same month. I was then offered upgrade or R125 airtime +5Gb for cost of R145 a month, which was gone start on the 01/04/2021 since I didn't want to pay for pro-rata .

In two hours I took this contract I call vodacom cancelation department to have this canceled since I had thought it through and felt it was expensive. The lady by the name of lerate told me the person who had sold this contract(upgrade) to me is the one who's gone do cancelation, which I find it unprofessional since she is working in the very same department. 25/03/2021 I called again to have this canceled I was told it is done and I was gone get email confirming this cancelation. Yesterday I notice airtime R125 and 1.2Gb of data recharge, which it was clear to me that cancelation was not done.

Yesterday I called vodacom cancelation 3 times. First time I called I spoke to Asanda Ndlovu who told me that someone was gone call me before the end of the day to do cancelation for me, which I find it strange as to why would I have someone calling me instead of her doing processing it since she too is working in cancelation department.. At about 15:20 I called again I spoke to Lerato Mzamo who told me that Asanda Ndlovu was gone do cancelation before 16:00 and I had explain to them I haven't been using my phone to do calls or use data becouse I didn't want to use the one for contract. I called again at about 16:20 but nothing have been done.. This is so annoying becouse number one It look like vodacom have untrained staff who can't do their work, I fail to understand why it so difficult to do cancelation while it was easy for them to do upgrade.that upgrade turn out to be something different from what I was offered and it such a shame that there's no reference number to the call. Just want this cancelation done and I want nothing to do with vodacom.. Never taking contract with vodacom again
