Eskom Electricity Token

I have purchased an electricity token on my banking app for R350 (lot of money) and my mistake was that I didnt check the previous purchase that I made and I mistakenly bought for previous meter number which is not mine and unfortunately the transaction went through, I immediately called Eskom and was given a ref number by Elelwani on the same day, the 2 -3 days down the line I called to follow up with the ref number and was told by Sharon that they cannot assist me as I was only requesting them to change from the incorrect meter number to mine (correct one) , then I got a call again from Eskom in my area that they cant assist me, which is really disappointing and the lady even said I should just consider donating that token to the wrong meter number holder, I told her I cannot do that I just need help , mind you electricity is expensive cant just give away 350 work of electricity away like that, and worse part is that the electricity token still with me and havent gave it away. please help.
