Vodacom reoccurring data bundles slapped onto my account

I am coming to the end of my cellphone contract and this month I am billed for a 30Day reoccurring 30 data bundle for February and another reoccurring 30 data bundle for March so a total of R166.72 added to my bill.

I called on the 13 March to cancel the reoccurring 30 day bundle which by the way I DID NOT PURCHASE. My history should show that I do not buy reoccurring services at all why would I if my contract is a Uchoose flexi contract so that do not get billed end of the month for any additional services.

The once-off 30 day option is what I select every month and not reoccurring. It is the 16 March and Vodacom technical department have not been in contact with me. I am in a Software Support role we have to troubleshoot any mistakes made to our customers accounts so why is Vodacom not doing the same?

I am in the process of upgrading but definitely having second thoughts after this mess being billed for something I have not purchased and this is not the first time the same thing happens with WhatsApp data bundles.
