No sharing data

On my husband's red package he is elligible to share data "Red Family Share". He has a lot of data and tried 7 times on the app to transfer to me, who is also on Vodacom contract. He follows the correct routine, and everytime it says "unsucessfully shared". We called Vodacom helpline, and they said the option is not yet operational on the app - but the button is there. They said to try the website - still could not do it. Then I tried on the app and could transfer data to my husband - so the function works!!!! We then called Vodacom again, they could not help, then referred us to UPGRADES!!!!!!!!! Obviously they could not help. Can you just activate this function?????????? Vodacom has terribly bad service - how do you not have competent staff and an app that actually works????
