OK, I must be misunderstanding how escrow works in this situation sorry.
I was assuming the escrow received the bitcoin, told the seller bitcoin was in account, then the seller sent the coin to the escrow, and escrow forwarded it on to the buyer. Does seller send directly to buyer, and once the tracking says signed for then you release the bitcoin?
Edit: Also my apologies for derailing! And being dense! Trying to stay awake over here after missing the Lealana earlier today!
not to step on anyone's toes by answering - but typically, the payment is sent to the escrow provider, the item sent to the buyer - tracking provided to all involved, then when buyer receives item and verifies it is as described they notify the escrow who would release funds to the seller.
if there are issues with the item not being as described, there could be further steps needed - really depends on what the issue(s) are.
