Thank you very much for your support.
I have just filled out the form so hopefully they may be able to help, but from what I have heard they only deal with very high transactions and charge a very high fee, I can't remember the exact amounts but it was way off what I am dealing with.
I really think they should help you, after all it was a mistake by you, if they are to be known as a reputable website, then they will indeed return your deposit, hope all goes well.
I once withdrew bch to localbitcoin and never got it back they said they couldn't. It was horrible and I lost my money

I'm sorry this happened to you. Always check over and over again the address you sending to. Take your time. It took you a long time to make that money you can spend a little more time to secure it and make sure it goes where it should.
