It's clear that iNetBet didn't notice what was going on until at least the last time the error occurred, which was on the 7th. It was on the 8th that they corrected the error, so it would appear that only a single day was allowed for them to contact the player asking for the money back, and them taking it back. It doesn't seem reasonable to assume that the player not replying within 24 hours is evidence of them intentionally trying to keep the money.
Given that taking back the duplicates was so easy, there was clearly no need for the players' permission in any case, and since the money was there for the taking, the player had not made an attempt to prevent it's retrieval either by spending it nor withdrawing it from Ecocard.
If it's reasonable for iNetBets cashiers to not see the "bleedin' obvious" from their outgoings at their end, it should be reasonable to conclude that the player didn't notice without any evidence that shows the player DID notice and tried to obstruct it's retrieval.
iNetBet are notorious for ignoring some emails, and it is the ONLY way this player could have contacted them in order to inform them of an error. Given that iNetBet make it such a chore to make contact and receive a response, they shouldn't be surprised if this player DID actually notice at an earlier stage, but just assumed that it would either be corrected in due course, or iNetBet would initiate contact.
Given how players often find duplicate transactions on cards due to the messed up way processors pre-authorise, and then take the money with a different authorisation code, with the duplicate dropping automatically after a few days, some may no longer see a double posting of a transaction as an issue that needs to be taken up right away.
Oddly enough, when it's the other way around, where players complain that the casino has taken the money twice because their statements show a duplicate transaction, they are told "don't worry, the duplicate will drop in a few days", and if the player accuses the casino of intentionally helping themselves twice, they are offended.
If we are to hold casinos to the same standards, then when something goes wrong that causes a deposit to be taken twice from a player, and the casino doesn't take the initiative to notice it, inform the player, and then correct matter, it would be fair to claim that the casino deliberately sought to profit from the inattention of the player by keeping quiet in the hope that the player would never notice.
