For the fourth time in a row, Verizon was recognized by J.D. Power and Associates for the best customer care among national, full-service carriers.
The rankings take into account on how well companies provide customer service via telephone, walk-in and online support. Verizon ranked first with a overall score of 766 (based on a 1,000-point scale). AT&T ranked second with 759, Sprint next with 746 and T-Mobile at 715.
The study was based on responses from 7,322 customers who contacted customer care during July through December 2012. MetroPCS had the highest ranking for non-contract carriers.
Verizon also announced earlier this week that it invested more than $134 million last year in the state of Washington to improve wireless service and coverage.
