This work aimed to verify, in a process perspective, the initial impact that recent law modifications exerted in an essential sector for Brazil, by applying the five dimensions of the quality theory. A total of 2,932 complaints about an important mobile phone service provider in Brazil were collected and classified. The dimension "reliability" had the highest number of citations, while the dimension "tangibles" had the lowest one. Results indicated that there was a significant increase in the number of customers' complaints, especially in the "responsiveness" and "empathy" dimensions. In conclusion, it was possible to verify that the increase was driven by greater consumers' awareness about their new rights, indicating that they have become less tolerant of the weaknesses of the service. The research has broadened the results on the subject in the telecommunication sector, considering this new variable in the Brazilian scenario; the call-center law.
