Instand money transfer voucher not working

On the 12th of July 2015 I have received a instant money voucher for the some of R800. When trying to collect the voucher at Burgersfort Engeng Garage Standard Bank ATM, the ATM produced a receipt that there were a break in transmission and no money was paid out. I went to another Standard Bank ATM in Burgersfort but after I have entered the voucher number the response I received from the ATM was that the voucher has already been used. on inquire at Spar they referred me to Standard Bank for rectification. At Standard Bank they told me that it would take up to three days to complete the investigation. Standard Bank ***.<br> We also experienced problems by getting hold of the people who work with this type of complaints at Standard Bank. I believe this issue could have been resolved immediately due to the fact that we are in a new computerized aged and all of the information is instantly available. I wish this issue to be resolved A.S.A.P. The ATM Teller made a mistake in a moments notice but the correction of the mistake cannot?
