Trader with trade ID 19354 please respond in the dispute

I have a case with a trader not responding.
Trade ID: 19354-e1dfcb4b-93d6-46bd-bcca-231d369f3571-094

I can be that he never received the dispute message due to network issues (see Restart your app at least once a day to avoid missed P2P network messages).
So if you are the BTC seller of that trade please get in touch.
