There is no Bonk balance at all. It wasn't a huge amount but I was just concerned that any further transactions would have similar outcomes, if indeed this is the final outcome.
My apologies if this is the wrong forum.
I can't access my account for whatever reason, nor create a new account but by looking at the "Swap process" from the Defi web wallet:

I can see that you get to choose the account you want to swap from, or swap to.
Are you sure you're looking at the "correct account" after you're swapping? that's probably why you cannot see them in your balance?
