I got the same call, and they said I owed a bad check and if I didn't pay it that day I would have a warrant Issued for my arrest. I called the company that the check was Issued to, and they gave me the correct number that it was referred to, and says that any company that says you will have a warrant issued for your arrest is fraudulent.  What they do if you do not pay is you would get a summons to appear in court; and if you don't appear then you could have a warrant issued. I have filed a police report and contacted the attorney general on this.
