What you wrote is what I always thought.
They clearly want to deceive you to get the funds from you by asking you to provide the seed phrase.
So you are saying Atomic Wallet Support deceived me by requesting me to insert my seed phrase into different links?
When I wrote Atomic Wallet about this, they claimed it was a safe procedure.
Another poster wrote that this is necessary to transfer the funds.
Well, it is necessary to access the wallet using the seed phrase so you can send the funds to another wallet of your choice but if they aren't deceiving you then they wouldn't told you to import the wallet on that link and would just told you that you'll need to use the seed phrase to import the wallet to another wallet provider so that you can manage your funds like sending funds to another wallet. Anyway, have you checked the wallet and is there funds on it?. If yes then you don't have to worry about it and just create new wallet and transfer the funds in there.
