You did the right thing. The extra money you spent in safeguarding your funds was a part of a wise attempt. Recently, I had an encounter like what you had. It was with Metagalaxy (Megaland), an old token I had that had its migration but I didn't know of until it was past. Someone sent me a link on how to go about it manually. I sensed something was off with that because it was unsolicitedly rendered. I moved out the token to a fresh wallet and attempted the migration. It dawned on me it was a link that led to a wallet drainer. It would've drained my funds if I had attempted to migrate in the first wallet. People should be very careful. Scammers are getting wiser.
