Any Experience with GEL (Global Edu. Logistics)?

Hello,

first time poster here and new to the international school community. My wife and I are beginning our job search and we’ve paid to attend a recruitment fair this coming weekend in London with an agency called GEL - Global Education Logistics.
Long story short, the communication with GEL has been terrible and we’re unable to find a lot about them online aside from their website. Does anyone have experience with them? Are they a legitimate recruiting agency or have we fallen into a scam?

Any help will be apprecited.

I didn’t find the right solution from the Internet.
