This really sucks that this happened to you. But you need to make sure you are confirming the information that is sent in PM's to you. I included all our our unique discord id's in the pm as I do every trade. You didn't check it to make sure you were talking to the right people.
If you look at the conversation I was in it will be different than the one you were in. If you continue to trade on sythe please look through some trading and newcomer guides so that this doesn't happen again.
