The only manual payments from coingateway that I remember seeing were the 10% bonus for buying with alts? They said themselves that when they were recovering the wallet from cold storage that all transactions were fine and were recorded on the blockchain (which I assume is listed within their transaction log on their site).
Before they released 10% bonus transactions they were doing too manual transactions which were stuck earlier and were being sorted by support tickets , they weren`t recorded
Coingateway doesn't give 10% extra anymore.
