Transferring of data between 2 accounts owned by same person a huge challenge!

I have 2 x Vodacom accounts.... I that I use on a daily basis and one for which my daughter has the sim card in the USA.

So, I ran out of data and am travelling, hence the need for a top-up! I went onto my Vodacom app and purchased a 3g+3G for days for an amount of R164. I was waiting for confirmation of this, when I realised that when I purchased the data, I was under the number that my daughter has in USA and accidentally purchased it on there as opposed to my primary number!!!!!!!!!!!!!!! Panicked and called Vodacom helpdesk and was told that there is no way that they can transfer the data to my primary number and that we have to do a data transfer from the number it was sent to. Due to the time difference and other challenges, I could only speak to my daughter today, she then inserted the sim card her phone (has not been using it fulltime), bottom line is that she is unable to transfer the data to the other number as she only has the option to purchase for another number? This is going to go to waste as she wont be using the data............... and I really need assistance with transferring the 6G to my number. I URGENTLY need assistance please as i believe that there should be a way that Vodacom can assist me on this? We purchased the data on the App, should we not also be allowed to transfer on the app? Why can't she transfer the data that was purchased from that number? Are there restrictions on who can and can't transfer top up data?
