Vodacom cancellation

I have called vodacom cancellation 1958 to get a cancallation quotation for one of my cellphone number as they are many. The consultant that pick up my call then said am in the wrong department since I need to call account department 1946 to get my premature cancellation.I then said no cancellation department show be the one to give me the premature cancellation quato as Account department will not be able to give me the quotation, then we went back and fought for almost 40 then he realiser that he can make the quotation himself then he just created that quotation and email to me without verification be done if am the account holder without asking verification question. I have experience a horrible service on that call. The call was made on the 09 June 2023 @ 12:21 that last 56 minutes for just one quotation. I can never understand why will vodacom compromise my safety by getting it to my profile without verifying if it's me. I have to question how simply will be for someone to call in an get our information without be verified.
