Just wanna warn you. I used this service a long time and everything was running fine but then one of my transaction was successfully exchanged but is still shown as "processing". I started a new exchange because the old one was completed for me but the new exchange from BTC to XMR is still not processing since 24-06-2022.
I tried to contact the support several times from different email adresses but there's no reaction.
Best regards
wait, so there was already an issue on your previous transaction but you still decided to start a new one? anyway, I found a Facebook page that says "bitswap" but it was riddled with fake reviews, other than that I can't really find any information about the website(which I always think is suspicious).
have you tried contacting them on their kakao talk account?
