These days all the telecom and cable companies are offering consolidated bills for their "triple play" combo of phone, video, and Internet services. But from what my readers tell me, that might prove particularly convenient for Verizon customers, since it means they can get all the company's billing errors in one place.

While Verizon's ability to mess up its One-Bill accounts is something we've seen before, readers continue to report new variations on the theme. "I decided to sign up for Verizon's One-Bill when I received a promotion for a $25 credit," one reader wrote. "Unfortunately, not only didn't I receive the credit but Verizon suppressed my wireless account so all I receive is a landline bill stating a total amount due, with no itemized calls. I wonder how many other subscribers didn't receive their $25 credit?"

It's interesting how Verizon's mistakes always seem to work in its favor. "My contract with Verizon Wireless had long expired and I decided to finally get a new phone one Sunday," another reader wrote. "When my bill arrived two weeks later, I had about $30 in overage charges. I never go over my minutes as I live in a rural area and get no service when I'm at home. Apparently I chose the wrong day to get my new phone. I went into the store on the 17th of the month and my month for my billing cycle didn't change over until the 19th. With the new phone I also changed my plan from 400 to 450 minutes at the same price. Essentially, I walked into the Verizon store with over 300 minutes and left with about 30 minutes. They prorated the last couple of days of my billing cycle, unbeknownst to me, and then charged me when I went over their proration. No one ever warned me that I would have only a few minutes to use for a couple of days while my billing cycle ran out. Thankfully, with some serious strong-arming on my part, they refunded the overage."

Customers who study their bill carefully - a necessity with Verizon - can run into some interesting charges. "Just got my Verizon wireless bill," wrote another reader. "I was billed 30 cents for two text messages. Small potatoes, I know. But who sent the text messages? Verizon did -- advertising new phone deals. If they do this on a widespread basis, is this a great racket or what? You send an innocuous text message ad, then bill for it. All those 15 cent charges add up to some real money after awhile."
