Haven't been receiving my mail (not IREA's fault but they have been notified that I am having issues with it) I can never get a hold of anyone to change my address now. So as a result of never getting my bill I completley forgot to pay my bill (my bad) what do they do? They shut off my power on a Friday while I am at work and close their offices before I get off so I go the ENTIRE weekend without electricity because they aren't open on the weekends... I hate IREA this place is a joke I'm from AZ where we have SRP 24/7 service on a 1800 customer service number. I'm not saying they have to do that but at least a Saturday would be great so I'm not out for two days.
