Appreciate the continued help, Danny - how can I push a raw transaction to their mempool, that was apparently sent via the Blockchain web wallet?
You can get the raw hex transaction from blockchain.info with this link:
https://blockchain.info/rawtx/9a2a0b1ba7949447acfba20829b1eda303828f172b1bbbf3c11101f9b7670b61?format=hexIn case you ever need to find the raw transaction at blockchain.info yourself...
Just change the usual /tx/ in the URL to /rawtx/ and then add ?format=hex to the end of the URL.
You can copy the transaction from there, and then paste it into the text entry box at the viaBTC link I provided.
