I'm not sure why I'm getting my bill a WEEK AFTER ITS DUE. No postage date on envelope and I'm seriously debating on giving these shiesty people a call. Not the first time this has happened and I'll be damned if I give these cucks any more money than needed. Can't wait to move. Thank God we use Duke Energy for electric.
