fraudulent calls

Called from (414) 763-2762, saying I got a grant ($14,000.00) and of course need info to verify. I  followed along with the call to see if I could get more information. Information received was a callback # 1 800 454 1390, steven smith was the grant manager that tries to get the information they already have verified. I was recently scammed on a credit card from someone in seattle washington and the address I was given was seattle washington . Please someone do something to protect us from these thieves.
