I was going on a tad over a year up until last week.
After getting my U Verse bill that had the real cost vs all the promotions I have had for several years I decided I would call them again, threaten to cancel my service and get my promotions back. This has worked every year for the past 5 or 6 years. This year they wouldn't budge unless I switched to their Direct TV offer. The switch forced me to pull out the Credenza and change out the set top boxes and I went ahead and cleaned everything up. After a look at the back of my AVR, I wonder if I could ever hook everything back up if I had to.
