ecocard said they can't disclose the timing on the request because "we are not at liberty to disclose such details of communication between our departments"
I was trying to point out that too many things occurred within a short period of time: conducting the weekly audit, sending emails to players, receiving the responses from the majority of players, sending the request to ecocard, getting funds back. All this happened in less then 24 hours if you believe Inet
Sounds like they have something to hide, and are using the usual "data protection" BS to hide behind. It's possible they don't want to reveal just how easy it is for a casino to yank back money it has already paid whilst for users, "all transactions are final".
There was an incident years ago involving Neteller, another eWallet that states "transactions are final", but a player found that a casino had effectively charged back a withdrawal two weeks after payment simply because they felt that the player had "not played within the spirit of the bonus" during the session that lead to the withdrawal. Trying to find out just HOW this could happen was also met by resistance and hiding behind "data secrecy". The suspicion was that the casino did not have to do ANY kind of negotiating or explaining, they just had to ask Neteller for the money back, and they automatically complied without seeking permission from the customer.
The timings strongly suggest that it's the same in your case, iNetBet ask for the money back, and EcoCard comply almost immediately without seeking permission from the customer. Not surprising therefore that they want the timings to remain a closely guarded secret, there just hasn't been the time for there to have been proper due diligence by EcoCard as to the validity of this request, nor any intent to involve the player in terms of seeking permission. It looks like the whole thing happened in 24 hours, from noticing the problem on the 7th during a weekly audit, to having the money taken back on the 8th.
It looks like there was an intent to keep those players who had not told iNetBet about the double payments in the dark, so that the money would already have been taken back by the time they noticed that action had been taken despite their not giving express permission. This seems to be based on an assumption that all these players were intending to keep the money for themselves, and that tipping them off in any way that the issue would be solved between iNetBet and EcoCard would give them the opportunity to move the money beyond reach by depositing it into casinos unrelated to iNetBet, and then presumably persuading these casinos to use a different withdrawal method. It would work because EcoCard would probably respond by freezing said player's account, which would mean that not only could they not deposit via EcoCard, casinos would be unable to pay back that way, and thus would be forced to deviate from normal procedures of paying back to source.
If it was happening en masse to all players for a week, it is pretty certain that a minority DID take advantage of the situation by ensuring the money was beyond retrieval.
It's a little known inside secret that when it comes to these eWallets, it is surprisingly easy for casinos to pull back withdrawals that they have paid, and this can be done without the customers' permission without any due diligence on the part of the eWallet as to the veracity of the casino's claim.
There was no need for any of the affected players to be cooperative, iNetBet would still be able to get the money back so long as it was still there.
Fraudsters KNOW this, so they don't leave ill gotten gains just sloshing around in eWallets, it's straight out in deposits for the next scam, or straight out into their banks, or better still, straight out of the ATM so there is no chance of persuading the bank to take action.
