Get a recorded msg on my ans. machine while I was out from a man who identified himself as "Alex" with a company name that was unintelligible. Caller ID said "NEW JERSEY."  Claimed to be setting up PAYMENT for us for an account with BERKSHIRE GAS.  We are in MASSACHUSETTS and DO have TWO accts with BERKSHIRE GAS, both of which are current and paid in full.  We have NO IDEA what this is about.  A search on this number brought up the name "ALEXANDER CASTRO in NEW MILFORD, NJ" but we DO NOT KNOW OR HAVE ANY RELATIONSHIP with this person, NOR would we be going through a third party to pay our bill to Berkshire Gas.  CAUTION.
