Product doesn't work

Earlier this month I purchased an electricity voucher from an ABSA ATM now when I got home to actual make the transaction as per instructions on the ATM slip I received a notification saying insufficient funds now I'm thinking how's that possible because as soon as the slip was printed out by the ATM a deduction aas made from my account so how is it possible that I don't have funds? <br> Following that I decided to contact Blue Label Telecoms again as per instructions on the slip and the call center agent informed me that this is rather common and at the back of my mind I'm thinking how's that not been fixed? Anyway the agent informa me to text 43471 along with the voucher pin and meter # and to this day I have not received any form of feedback nor coms from either ABSA nor Blue Label Telecoms and yet I had to go and purchase another voucher since this one wasn't working now from ABSA's view shouldn't there be an oversight to checl on their partner companies to see if they actually deliver? And what about Blue Label Telecoms?
