Vodacom data transfer not possible...

I often have lots of prepaid data left over every month. Vodacom regularly reminds that this can be transferred. (I am still not sure if I can transfer it to another person or myself for the following month.)

However, I've tried often to do both, but without success. I also tried Vodacom to assist in getting this fully paid-for-data not going to waste but not with much success either.

Seems Vodacom would like not to help. And, making money for no value add along the way. If they really wanted to - they could make this much easier!

(Seems I should make use of another company's SIM card as my phone can take a dual Sim.)
