Mtn data

Hello Peter i bought a Mtn data for my mother with my Capitec app,unfortunately i selected the other number that shes using that doesn't have internet,i called Mtn that i made a mistake and want them to transfer the data to the active number and I was told to go to Capitec and and ask for prepaid statement highlight the transaction and write the number that i want the data to be transferred to ,i did that after weeks waiting i received an e mail saying they cannot reverse or transfer the data for me .my argument is what does that mean ?meaning thats the way they treat their customers ?if them as the service provider can't assist who must?and why i was sent to my bank for a statement if they knew from the start that they cannot assist?i am not crying for my R99 data here my problem is the time,energy and the rist i took to go to the bank queues during this covid time for what to be told that i can't be assisted?i am very disappointed on Mtn.
