Option to transfer data on vodacom is a reap off!

So I my niece asked me to buy data bundles for her from Vodacom. I went onto my banking app, purchased a 1GB bundle for R149, I immediately realized that my phone number was selected by default, I forgot to select my niece's phone number.

I then looked for the data transfer option on *135#, and the I got an error that says "The number you are trying to link is not compatible for your payment plan".

So I called customer care, I spoke to a consultant who then told me that there's no way for me to ever transfer that 1GB to my niece, I have to buy another data bundle and select the correct number. Since I don't need the data bundle that was intended for my niece it means I have wasted a R149 on something I'm not gonna use!
