If you want to get in touch with AIR team another quick way is to join their telegram group :
https://t.me/theairplatformJust got these info about their website , that actually redirect you to old ICO site that has been taken down:
"The portal site belongs to a commercial partner, called TokenInvestor, so it needed to be closed for commercial reasons. - snip -.
www.sphre.co will undergo an update, so check back for all the news and updates. - snip -. The website update should be completed in the next week or so, as we want to put some more design thought into it."
Also regarding the matter of people that still have issues with tokens transfer thay just shared with me ( on public telegram group) these infos:
"we are no longer accepting target addresses at the portal site, but now have a list of all participants whom did not have time to enter their details, and we will be in contact directly in order to gather these in order to ensure that all participants receive their tokens.
We communicated the closure of the portal 5 days in advance of closure to encourage everyone to complete their details, and this was completed via email update."
So seems like there are several channels of communications opened and at the moment no one has run with the money.
