Sure – So what happened was that I cancelled the TX twice in Grim wallet, and I thought the first cancellation had went through before the TX was broadcasted to the network, because the UI appeared to allow me to send the transaction again (and cancel it again).
The dev of Grim wallet assisted me, they said that this can only happen when a Tor transaction is used (as opposed to a slatepack). Unfortunately, Gate only supports Tor transactions, and not slatepacks, like TradeOgre does (which is way more reliable).
Actually, checking the Kernel ID by clicking on the first transaction in Grim revealed that TX ID had actually went through. Grin Blockchain Explorer
So I resent my details to Gate’s support team informing them of the correct TX ID (Kernel) and a link to the block explorer above. They replied back with a boilerplate answer saying my deposit was still pending crediting, which should not be the case as over 700 blocks have elapsed (they credit deposits after 300 blocks).
Actually, I don’t even see my GRIN deposit as crediting, it simply does not show up in the list of recent deposits.
I’m still following up with them to get my funds back.
