Has that really not happened to you or someone you know? It is (typically) eventually recovered, yes; and you can often understand how/why it happened. But it definitely happens, and requires manual human intervention for fixing. Here's 2 incidents that happened to me or friends in the last month: - took a trip to the neighboring country, my friend tried to take out money from an ATM; first two transactions failed, third succeeded (at the atm). In the bank though, all "succeeded", and money were gone (first 2 eventually were reversed with manual intervention). - I sold a house (in a remote mountain village), buyer sent 8100EUR from Germany, 78xy.z EUR made it to my personal bank account. Apparently due to multiple currency exchanges, but this is a SEPA transfer between two accounts both denominated in EUR, this was absolutely not supposed to happen and nobody was able to articulate exactly "why it happened" (or even exactly what happened). For this one the buyer decided to just eat the loss and sent me an additional 300EUR.
