Electricity voucher invalid

I normally purchase my electricity through the Capitec Banking app and never hd any problems. Yesterday at 8:22am, I purchased electricity worth R60 and received the token. Upon inserting the voucher number, I received an error message. I tried over 5x to use this voucher and its not valid which is an inconvenience. I then purchased electricity via FNB immediately after that and the electricity loaded successfully. So the error is not with my meter, it is with the token. I logged a query this morning (11/09/2017) Ref: ********** 2 and spoke to your consultant who confirmed that the transaction went off my account. I need to know if I will get my refund or another token. It is the first time happening. I'd appreciate it if you treated this as an emergency because it really has inconvenienced me.
