called and said they are a police officer. wont give me the name or police station where they are from

Have received calls from same person before using different names and saying they are from the American Law Offices.  This time he said (in a very heavy accent) that he was Kevin Smith from Financial Crimes & Enforcement and calling about a claim against me.

Said he had a claim against me for an unpaid loan; I told him I didn't have a loan and that they needed to stop calling me.  He got really angry and kept trying to say I owed money I know I don't owe.  I finally told him that their scam didn't work and they needed to stop calling me.  I hung up on him!

officer allen jones called today, ,, yea right. what right do these people have to call me// time and time again. do they not know that the thick accent is a dead give away to who they are.

They are calling saying they are going arrest me if I don't call this number 9046471408 about a financial claim against my name
