A number of different controversies and criticisms have surrounded Comcast for various reasons over its recent history. Customers of the telecommunications company report low levels of customer satisfaction on both service and cost. Comcast has also had several customer service scandals, the most notorious of which featured a representative not allowing a customer to cancel his service. This clip went viral. Comcast has also been widely criticized, most publicly by Netflix, for its position against net neutrality, the principle that all traffic on the internet should be treated equally.

Low customer satisfaction

In 2004 and 2007, the American Customer Satisfaction Index (ACSI) survey found that Comcast had the worst customer satisfaction rating of any company or government agency in the country, including the Internal Revenue Service. The ACSI indicates that almost half of all cable customers (regardless of company) have registered complaints, and that cable is the only industry to score below 60 in the ACSI. Comcast's customer service rating by the ACSI surveys indicate that the company's customer service has never improved since the surveys began in 2001. Analysis of the surveys states that "Comcast is one of the lowest scoring companies in ACSI. As its customer satisfaction eroded by 7% over the past year, revenue increased by 12%." The ACSI analysis also addresses this contradiction, stating that "Such pricing power usually comes with some level of monopoly protection and most cable companies have little competition at the local level. This also means that a cable company can do well financially even though its customers are not particularly satisfied." In 2009 Comcast rebounded on its ACSI rating for television and Internet services, moving ahead of Charter Communications and into a tie with Time Warner Cable.

Criticism of Comcast

When the cable television needs assessment report for the city of Fort Collins, Colorado, February 10, 2004 which was required for Comcast's franchise renewal, the city's independent consultant found: "Approximately 62% of the respondents, though, were very dissatisfied (along with another 25% who were dissatisfied) with the cost of cable television service." "A majority of the respondents were satisfied with the friendliness and courtesy of customer service personnel. Overall, approximately 43% of the respondents rated the cable company's performance as fair, 30% regarded it as poor and another 30% rated the cable company's performance as good."

Criticism of Comcast

While Comcast does operate some of its own customer service call centers, it also outsources customer service and some technical support to Convergys Inc and until recently Transcom WorldWide, both third party call center companies.

Criticism of Comcast

On October 1, 2008, J.D. Power and Associates published its annual customer satisfaction survey for the nation's top 10 largest cable and satellite television providers. Comcast scored in the bottom 5 for each region of the United States, including 10th in the East Region. One of the largest internet based consumer-review services, Rateitall.com reports the average consumer review of Comcast as 1.6 out of 5 stars, based on a total of 511 reviews to date (2014).

Consumer affairs blog The Consumerist named Comcast "Worst Company in America" in 2010 and 2014. The company received the "Golden Poo" award to its Philadelphia headquarters in commemoration of the victory. The company also finished in the "top" three in 2008, 2009, 2011, and 2013. Since 2006, it has received more Golden, Silver and Bronze awards for poor customer service performance than any other company in the country, including Wal-Mart, Bank of America, and Ticketmaster.

Comcast has made efforts to improve customer satisfaction, including the Comcast Cares Digital Team. The Comcast Cares Digital Team began when then Customer Service Manager Frank Eliason decided Twitter would be an ideal way to communicate with customers. In 2010, @ComcastBonnie won the Customer Service category at the 2010 Shorty Awards.

The 2015 ACSI survey placed Comcast at or close to the bottom of primary company rankings in TV, Internet, and phone service.

The 2016 ACSI survey placed Comcast in the bottom half (11th out of 14) of Internet Service Providers and 8th out of 13 on subscription television service. The 2016 Consumer Reports' telecom service Ratings reported that Comcast was among the bottom dwellers in overall customer satisfaction.

Frequent complaints about Comcast's service include "stuffing" bills with unnecessary services, hidden service fees, outsized cancellation fees and improper credit checks.
