Customer service problems in the U.S. have hit unprecedented levels, and Americans have become increasingly aggressive in their efforts to address those issues, according to new data.

But experts say multiple factors are contributing to the spike in dissatisfaction from consumers and urge frustrated customers to keep that in mind when choosing where and how to direct their complaints.

A recent survey released by Arizona State University’s W.P. Carey School of Business found Americans are experiencing record-high problems with products and services, with 74% of customers reporting issues, up from 66% in 2020 and 56% in 2017.
