They said we won a lot of money..?

Calls my business on an almost daily basis.  I accidentally hit a number key on picking up and the caller went off extremely rudely and hung up.  I called back, got a recording for "Hudson Energy Services."  If they call again I will gladly tell them all about there rude employees, and they will never get any information from me.

Said they were calling from Hudson Energy Services.  Wanted information off my National Grid bill.
