I had to pay late fee twice, because my check got lost and delayed in the mail.The Post Office blamed them and they blamed the Post Office. Nobody apologized. I have an excellent record of paying bills. They were still rude and inconsiderate. Suggested me to pay on line. And I don't do that. So every month I physically go there and pay my bill. My electric bill is pretty normal, I have no problem with that. But I don't understand and agree with a whole lot of other stuff added to it.
