Caller: Crypto investment refund related

I received a call from a service representative stating i was owed money for bitcoin i invested in some time ago and was owed money due to their company closing down and they stated that the government instructed them to refund their clients... I dont have bitcoin even though i explained this to them, they insisted i waa owed the money after i confirmed my name and they wanted access to my bank account or wallet and my email address. When i began question him he become aggitated and a little arrogant , i ended and blocked the number .
