Paragon Invest Money Transfer Problem

While sending USDT, I wrote the correct address, I even used copy-paste. But I chose the wrong network. My cryptos didn’t reach them. The USDTs didn’t reach them, but I don’t have them either. So, where are they? They told me they got lost in the network. Where did my $1000 go, and how can I find them? They said it's impossible. I am very upset.
