Verizon Still on Top in VocaLabs Study of Customer Satisfaction

MINNEAPOLIS--(BUSINESS WIRE)--Jan. 18, 2006--Vocal Laboratories Inc. (www.vocalabs.com) today announced the results of its ninth quarterly SectorPulse study on the quality of customer service among the largest wireless phone companies. During the three months ending December 31, 2005, Verizon Wireless (NYSE:VZ) maintained it's lead but slipped from an "A" to a "B" in overall Caller Satisfaction and retained a "B" in single Call Completion.

T-Mobile (Deutche Telekom AG) and Cingular (NYSE:T) remained behind, retaining "B"s in Caller Satisfaction but dropping to "C"s in Call Completion.

AT&T Wireless customers not yet switched over to new provider Cingular still report less satisfying service levels, but with a diminishing number of legacy AT&T customers remaining, we are combining them with Cingular scores in this report.

Sprint's (NYSE:S) grades were also unchanged from last quarter with a "C" in Caller Satisfaction and a "D" in Call Completion.

VocaLabs CEO Peter Leppik comments: "While overall performance remains lackluster, the quality of customer satisfaction among these carriers has improved over the last two years by a statistically significant amount and a greater percent of calls are now being handled entirely by automated systems. But there are notable inconsistencies among the four companies which indicate that some are dong a better job of delivering quality service while keeping expenses manageable."
