Top 10 Companies With the Most Customer Service Complaints on Twitter: AT&T Worst, Apple Sixth
We analyzed thousands of customer service complaints on Twitter (from 13 Aug 2010 to 16 Aug 2010), to find out which corporations caused the most frustration.

Data was first collected from the Twitter Search API, using a search for “customer service” together with any one of: fail, sucks,worst, poor, bad, terrible or awful. Tweets that included links were filtered out, as were re-tweets, to maximize the likelihood of personal experiences and reduce tweets about articles or stories (e.g. Jet Blue, Santander and O2 customer service stories were prevalent over the survey period).

The extracted tweets were placed into an Excel spreadsheet and manually verified over the course of a day, to check the validity of the complaints (i.e. to ensure that tweets like “I’ve never received bad customer service from X” weren’t included), and to extract the correct names of corporations (i.e. some people use the full company name, others use Twitter usernames, hash-tags, or abbreviations). Where described in the tweet, we also recorded the cause of the frustration, e.g. slow service or rudeness. http://www.groubal.com/top-10-customer-service-complaints-twitter/
