Only 4 eu countries can participate with the EU Gong Cha event, why SE???

[VerdeLuck]

There are 3 gong cha USA sites, and they all have different coverage for stores and states
gongchausa.com
gong-cha-usa.com
gongchausaofficial.com

I have no idea what is and isn't being covered and who is and isn't a part of this promotion, SE customer service has been pretty unhelpful as well in figuring out who is and isn't a part of this.

update to this, I put in another support ticket and NA support was unable to verify which of the 3 companies named gongcha USA they are partnered with, and asked me to instead google locations and manually call the managers of each to ask if they are participating to build my own map.
thanks customer support, big thumbs up! You know it's a quality collab when one company who is collaborating is unable to verify which company and entities they are partnering with.
