A new study from J.D. Power released today ranks AT&T as the best customer service provider among its competitors. The report focused on service provided online, over the phone and in retail stores. But despite this latest bit of good news, AT&T says it isn’t done improving its customer service program.

“There is nothing more important to us than listening to our customers and continually improving their experience at every opportunity, and it’s a job that’s never done,” said Ralph de la Vega, president and CEO, AT&T Mobility in an official press release, adding, “We look at customer service not as a department but as a discipline that must be applied in every part of our business, by each employee, for every customer.”

In the past year AT&T has rolled out a number of improvements to its customer service program. Customers can now schedule in-store appointments ahead of time, and the carrier also offers faster checkouts when purchasing a tablet in-store. Its chain of retail outlets have also been remodeled to its chain of brick-and-mortar stores. The network now boasts the best customer service and the fastest 4G LTE.
