I think you are safe... as stated on their website:
Your funds are safe
For redeeming the funds after expiration, you can use a tool we've developed specifically for this purpose - see Gentle
For 2of3 recovery see this guide here
Bro, I have just mnemonics of that wallet. And I don't understand how to use that tool much. Can you guide me please. Seems it is asking for any type of zip file to upload.
Greenaddress.it will send you a zip which contains the nlocktime for the transaction if you have email registered. You can set the time for it to be locked or can't be confirmed till that specific block, default is 90 days. Go to
http://greenaddress.github.io/gentle/ and key in your mnemorics and put your zip file. Next, the transaction to push will have the inputs and the private key. Once the status goes to 0, you can push it and it will confirm very soon. The private key is needed for you to spend it elsewhere so you have to import it into another wallet.
I have some funds in my greenadress wallet. And now its showing service is currently unavailable. Please tell me, is it gone scam or its a temporary unavailable issue.
I used this site to check the status of the site in question
http://downforeveryoneorjustme.com/greenaddress.it...and I also tried to access the site, it's currently up and running, no problem with page loading.
Have you tried to contact your ISP?
That site only pings greenaddress.it to make sure that it isn't down and is hence not accurate.
But it is indeed up again.
