dept. of law and investigations officer alex william calling home phone, leaving message about serious matter Internet

Recieved a message on the answering machine from an "Officer Alex William" saying he was from dept of law and investigation and needed to speak to me about an important matter that he could not disclose on a voice message and that i should try to call him back at a specified phone number-called tn-got no answer. person leaving message spoke with india accent. looked up this company on web and was not surprised to see that other people have posted on ripoff report of similar calls-of course they were called by a Mark Williams, my guys name is Alex william. Huh, wonder if they are related? Of course my feeling now is that this claim of needing to speak to me is total crap!
