Ever. I've been with this company since they were Time Warner, years and I've always paid on time. I had my plan changed a few months ago because there was a huge price increase they did without telling me they were going to do it so I cut the service down to the bare bones. They changed my payment due date so I wasn't exactly sure when I was due. I called and made an arrangement to pay next week when I get paid and the system even acknowledged it.
Then the crazy started, for the last three days the system has been sending out reminder after reminder that I'm late and pay now or I'll be unplugged. Again, I've never made an arrangement like this with them before, this time was unusual. Email, text and even a snail mail letter arriving within days of each other saying the same thing. If I say I am going to pay by a certain date, I will. I ended up pulling money out of my savings today just to shut them up. They have payment arrangements but will bug the hell out of you between now and when you have to pay to pay up. Are they going to go broke if I pay on the date agreed upon? Not likely. Again, don't bother making payment arrangements with this company, they don't understand the concept.
