Was it a double transaction?
I'm reading a lot of conflicting information some saying they have checked their statements and there are double transactions and others saying it was just double SMS notifications but one transaction on their statement.
From what I've been reading, it's actually just double SMS notifications, not double transactions, although some people claim to have had double transactions occur. I think if this is indeed the case, and can be proven, then the bank will reverse one of the transactions.
From what else I've read, what has happened is that the funds were "reserved" at the time of purchase, but apparently that reservation only lasts 10 days, after which, if not claimed by the merchant, it falls away and the funds are available again. However, the merchant has 6 months to process/claim that transaction, at which point the money is actually deducted. Now this I was not aware of, so I think implementing a system that SMS's you when a reservation expires, would be a good idea, then you would know that the money hasn't been deducted yet, but could be at any time (doubt any merchant would take anywhere 6 months, though, more like the month or so like in this case), and that you know not to spend or budget it.
Been interesting learning this, as I didn't know about half of it.
