This is all very well, but far from warning people about this temporary glitch, I have just received an email PROMOTING these deposit methods. This is VERY poor on their part, as this just means more and more users will fall victim to this glitch, and leave an even bigger mess to clear up.
Even worse for Neteller, it increases the chance that someone will take this issue to the authorities, and their failure to warn users to refrain from using these troublesome methods till the problems are resolved is going to look bad. It will also lead to users blaming their banks and UKash for the problems, and these institutions may find themselves subject to investigation by the FSA even if they have nothing to do with this issue. The problem is that these institutions are in the line of fire, whereas Neteller is shielded by being offshore (Isle of Man), hence users in the UK have only one party to put real pressure on.
It could lead to UKash pulling out of Neteller.
Bank customers have even more rights, as if a transaction is debited from their bank, but never makes it to the other end, the banks have a responsibilty to investigate the problem and ensure the customer is not left out of pocket, and if they don't, the financial ombudsman will make them.
Given that the Neteller statement shows it as "declined", there is enough evidence there to show that the money has vanished in transit.
Banks will probably advise customers to wait a few days in case the transaction reverses automatically, or the issue gets fixed by Neteller, but after this, the customer can start quoting the regulations in order to force the banks to take action.
