A massive inconvenience

I tried to purchase a R50 Kauai voucher using the Vodabucks program. This was today, 15 February around 2:30 PM. I had to redeem 220 of my Vodabucks and pay in R19 with my card, however the transaction failed but the system still took my Vodabucks, and I never received my voucher. I am requesting that my 220 Vodabucks be credited back to my profile immediately. Respond to me with feedback by email as I cannot take calls during work hours.
