form letters

So I received my "response" from Pepco right on the 48 hour button. Nifty how that works out. And no surprise it was a form letter:

Dear Ms. Jackson,

So I have multiple problems with this "response." One, it is a form letter, which is not a response to me at all. It does not address my problems, it is a do not reply address so there is no way to engage with C. Lamont Reddon. Since their phone customer service reps were similarly disinclined to engage with me (ending the call mid-sentence with a thanks and good bye), I essentially have no way to communicate with the company. I have no idea what their "investigation" will entail, because this letter was written to be applicable to every complaint they get. My "investigation" could be easily resolved by sending someone out to read the meter, or by simply asking me for the photo of the meter that I mentioned in my complaint. I will be mentioning this in my public service commission complaint.

Additionally, this letter is completely unclear about whether or not I should pay the current bill. It says not to pay the disputed portion, but I have no clue how to calculate that since they overbilled by an undetermined amount. I'm not claiming to have used 0 kWh, but I have no idea how many kWh I actually used since I checked the meter over a week after the billing period ended. Should I calculate the bill based on that number and just rework the math myself and pay that? Because that would be technically incorrect as well. I suppose we will pay the whole bill and then wait for the credit once they catch up the correct meter read. That irritates me for a variety of reasons, the primary being that the extra money I pay for their screwup would have been earning interest for me during the time I wait for them to correct the problem. I'm seriously considering generating a bill for the interest after they correct it and sending it to them. It would be a small bill, like a couple of dollars tops, but it is sort of the principle of the thing at this point.
