Vodacom consultants not knowing their products

After being with Vodacom 17 years (prepaid & contract) I decided to get a topup contract for my upgrade. After asking at two shops if I can use the topup amount to buy bundles for another number and no one could give me an answer (not even a manager), I phone 082135 and asked a consultant which answered me with "yes". So I upgraded and then asked the consultant that helped me with the upgrade if it was possible and he confirmed that it was possible. After activation of the service I tried to buy a data bundle for another number and it told me I do not have permission. I phoned 082135 just too be told that it is not possible to use the money I pay for to do with what I want. I would advice anyone who is thinking about a topup contract to get prepaid or better yet join another provider who has better deals and much more freedom.
