The 3rd part in "Summary" says the transaction is included in block # 317750
You can click that number to check the block's information.
In the Block information summary it says "Relayed By Eligius"
take the link above and replace the transaction ID of the example transaction with YOUR transaction (that sent the 1.5 fee)
Do the same process to check who it was "relayed by"
Tell us who the block was relayed by and we'll help you find a way to contact them if we can.
