I bought some Tomochain tokens over a year ago and have only just seen there was a swap last December and I missed it. I had left them on a Ledger Nano all this time. Do you think my tokens are lost now or will I still be able to swap them? I messaged customer support on the Tomochain site but they havn't replied yet.
The probability for you to swap it is very small because it has been months after the swap, but everything is possible in this world.
I advise you to join their Telegram channel and ask it there directly:
