A company calling itself Washington Gas and Energy Services has been calling my home repeatedly (during dinner hours), offering a deal with PEPCO for "locked-in reduced rates". It sounded too good to be true, and it looks like it is indeed.
I some research on the company, and while it presents itself as a Washington Gas affiliated company, all of the comments that I found onlne were VERY negative. It sounded like a scam, and it turns out that it is.
If you get a phone call, watch out, because they are very quick to solicit your PEPCO account number. Most of the negative complaints that I heard and read were from persons who had given the PEPCO account number and gotten sucked-in to a very bad deal.
