I received a phone call from 410-770-9636 today.  It was a robocall from a competitive electric supply company.  I don't know who it was, but it pissed me off.  The next time I'll wait to hear who it was from, because when I called it back, a message said it wasn't a working phone number.  Once I find out, i will report them to the Maryland PSC.  PS - I am an energy broker.
