Guild Wars 2

So I read that we can still spend our left over guild influence at a merchant in guild hall or guild intaitve office, I have looked for 3hours and I can’t find any merchant or person to talk to, I have even googled and searched forums, we have over 1k and id like to trade it for something. Can someone pls tell me where I do this at?

Thanks!

Afaik, you can only trade in quantities of 10,000s. Anything under and the vendor leaves
