ConEdison’s online service takes – 10 days

I emailed ConEdison on 3 June 2004 to inquire about stopping electric service to my current residence. Only today, 10 days later, did they reply. Although this is better than MCI who has NOT replied yet, 8 – 10 days to reply to an email is NOT acceptable.
Utilities do one thing right and that’s delivering our phone, gas and electric service. HOWEVER, do they realize how much money they could save by moving things online?
PSE & G (in NJ) does it – but what about the others. Must I make calls to my utilities and wait on hold for each one?
