Here's a look at some of the biggest customer service nightmares that cable operators have grappled with this year.

In today's spotlight, FierceCable takes a look at the top 10 cable customer service nightmares of 2012. Comcast leads the list, as it has dealt with challenges ranging from exploding set-tops to employees crashing vans into homes.

Five multichannel video programming distributors (MVPDs)--AT&T U-verse, Verizon FiOS, Cablevision, Dish Network and DirecTV--have lined up to deliver an American Express-branded digital channel that the credit card company is using to promote its capabilities.

American Express said it has launched interactive advertising channels that will help promote its credit cards to Cablevision, Verizon FiOS TV, AT&T U-verse TV, DirecTV and Dish Network subscribers.

Cablevision is demanding that the Communications Workers of America halt a phone campaign in which it is telling subscribers who lost service after Hurricane Sandy that they need to call the MSO to request refunds.

Goldman Sachs downgraded Cablevision stock to a sell rating on Thursday, predicting the MSO's capital spending and stiff competition from Verizon's FiOS TV will cause its stock to drop by about 20 percent to $11 in the next year.
