At this forum is a representative of this service (blockchain.info)?
This is their ANN thread
Blockchain.info - Bitcoin Block explorer & Currency StatisticsBut the OP of it has been inactive in the forum since 2015 so the only way to keep on conversing with them is through their support / ticket.
I ask them to help me find the one who carried out this transfer. I want to ask him to give me back the coins and to know how it had happened. But the service does not provide any information.
They won't know on who's the one responsible for stealing your bitcoin and we all know the attitude of a robber, they won't return something that they've stolen.
its already useless to have these kind of steps or trying out to contact those persons, even if you do make emails or on support thing they wont really do anything at all yet they dont have the capability on such recovery and as already being said to their terms you would really know that they are not held responsible if theres such loss because it would be entirely on wallet holders responsibility on handling his own funds.
