Kept calling and hanging up

called at 3:15 am!!!!!!

Got a call on 12/12/2014. No message.

Telling me they want to reduce my bill but for me to give my info claim to be a company that works with pseg

Telling me they want to reduce my gas & electric bill by 40% however, they wanted my account number, and i told them that i did not have it, and they should be able to get this information from my energy provider.  The individual was very pushy insisting that i should have an old bill or cancelled check showing the account number.  I told them that I can call the energy company to get a copy of the bill, and will verify that the call is legit.

Caller: not sure of the name
