Day light ******* on prepaid electricity

On the 25th September I bought prepaid electricity for an incorrect meter. After going to the branch I was told they won't reverse it as I have received the token numbers. What I fail to understand is that with the token that was sent, I can't use it anywhere and capitec insist on not refunding me.

I must keep this token for life knowing I won't use it? What this bank is doing is day light *******
