After all, the information he provided shows that it is a mistake in the deposit.
Why you can judge he was doing mistake on the deposit? I can see the address already received 0.06 BTC while he said only 0.02 BTC arrived in his account... do you think blockchain got manipulated? AFAIK there's no mistake from his side, the problem is from 1xbit.
I didn't say it was the user who made the error with the deposit. As you wrote, it can be seen that 0.06 BTC has been sent, so unless something we don't know has happened before then it is clear that the error is on the 1xbit side. Blockchain doesn't lie.
Yep the representative hasn't disappeared but it's useless since the problem will be ended like many unresolved cases before.
If you think this information is more helpful for this user, that's your choice. I tried to help him by informing him of the possibilities he has.
