Per a report by 24/7 Wall St., T-Mobile USA, which is also amongst the top four mobile carriers in the U.S., has been rated as the third-most hated company in the country.   

"Last year, plans were in the works for AT&T Inc. (NYSE: T) to buy the U.S. branch of this struggling wireless carrier from its parent company, Deutsche Telekom. In December, AT&T cancelled those plans after the Justice Department sued to block the acquisition, saying the deal would 'substantially lessen competition' in the industry. It appears that Deutsche Telekom is is now stuck with what is increasingly becoming the black sheep of the big four U.S. carriers," noted the 24/7 Wall St. report.

The report did not indicate the basis on how the most hated companies of the U.S. were determined, but it seems from the report that customer service, unhappy customers, and customer drop-out rates have put T-Mobile USA as the third-most hated company in the U.S.

Furthermore, 24/7 Wall St. also reported that "T-Mobile's 4G network in the U.S. lags the other three carriers, and customer satisfaction is tied with AT&T mobility as the worst among wireless carriers, according to the ACSI. T-Mobile also rated as one of the worst in customer service according to MSN/Zogby's annual poll. The company had an extraordinary net loss of 1,558,000 subscribers in the first three quarters of last year, out of the roughly 33 million it had at the end of 2011. During the same time, AT&T and Verizon Wireless continued to gain customers."

T-Mobile seems to have improved its position in the U.S. with the recent collaboration with the smaller carrier MetroPCS. The company also recently announced that it will finally offer Apple products to its customers. These changes may slightly improve customer satisfaction; however, it will be interesting to see how long the company remains in the top 10 most-hated companies list in the U.S.

JC Penney ranked at number one followed by Dish Network Corp. in the second position. Surprisingly, per the report, Facebook is the fourth-most hated companies in the U.S. Previously, 24/7 Wall St. also reported that T-Mobile will disappear in 2011; however, considering the carrier is still in existence, the report should be taken with a pinch of salt.
