Double Debited account !!!

On the 24 of March, I had purchased tickets online with iTicket. The amount of R950, for which I had booked tickets, was taken from my account. This was not a problem. However, Today I discovered that the R950 was debited AGAIN, as of yesterday ! !! Upon phoning iTickets, I was told that it is not their fault but that of Standard bank. How ridiculous is This!!! I purchased the tickets from itickets and they did not hold themselves responsible and said standard bank was having TECHNICAL ISSUES. Out of options here and disappointed!
