Poor Service when trying to delete VodaPay Account

I registered for the VodaPay app but then decided that I wanted to delete my account.

I have not been able to find out how to delete my account and having promotional emails sent to me. I enquired with *** in May reference EC-1E9Z-2I57XX and still haven't received a response and it is July.

I also tried speaking to a consultant (Ayanda Mdletshe) over live chat about deleting my account but they told me to just delete the app but when I said I want my details and email address removed from the database, they said I would continue receiving the emails even if I am not a customer of Vodacom which is just bogus - clearly the consultants have not had adequate training. I understand that I should be able to log into the app to update my email subscription preferences but have not even be able to do that because do not receive a OTP to my number.

So at this stage, I just want all my details associated with VodaPay to be deleted to stop receiving promotional emails and it should not be this difficult to have this information removed.
