Well dude looks like you aren't getting your money back. Kind of a big mistake on your part, but any financial business should have the kind of customer service that gets you your money ASAP and works out the issue behind the scenes for themselves. Too bad these businesses are so new that customer service is not yet #1 priority for them. Hopefully you didn't lose too much.
I resent that. You have no idea what needs to go on in order to get the funds back for this customer who sent it to the wrong account. We have to chase after the person who has the funds and get everyone to agree. The fact I exchanged many and many emails and posted on this thread shows we have the best customer service. Please try our service before making comments about our supprt.
Asking the other account holder for permission to remove funds that don't belong to him is bullshit. It wasn't his money to provide permission to remove from his account. Mt Gox should have froze or removed the funds immediately from the other account holder upon your confirmation that this was a valid issue. They should have provided you the go ahead to reimburse user or send funds to real account at the same point. Obviously your going to come back and say there is all kinds of red tape that needs to be addressed to obtain funds. That's fine, but reimburse customer immediately while you and Mt. Gox work that out. That would be considered the best customer service.
User who made a mistake loses on this rally while his funds are tied up with red tape. And Yes I know at the end of the day it is his fault for making the mistake with account number.
I agree with officialsavage on this issue. This situation happens with banks all the time but once the customer or the bank employee realizes the error, the bank fixes the transaction without permission from anyone. I'm not sure which laws or rules apply but it is Standard Operating Procedures (SOP) for banking.
This might be a little tricky for MtGox accounts with no real identity other than a username or email address but CYA...
