There's many different types of things called tri-hub.
I'm assuming it's the payment processing system. I've never heard of it before. If you need support for it, please post in the payment Support Forum.
If you want to find out more information, then why don't you simply do a Google Search for "Tri-Hub Transactions" which will take you to their website. You should be able to find all the information you need there.
Polite note - Please stop the name calling, even if it is reasonably polite name calling

. Robsta did have a valid point that perhaps this wasn't the best place to post your topic.
