How Poor Service Affects Brand Loyalty

You know the drill. Something breaks, or an unexpected charge shows up, and you dig out the customer service number. Then comes the maze: press 1, press 3, say “representative” four times to a robot that keeps misunderstanding you, and finally a chat window that offers a link to the same FAQ page you already read. If that feels worse than it used to, you’re not imagining it. The numbers agree with you.

The scorecard is slipping

The American Customer Satisfaction Index tracks how people feel about the companies they deal with. Its Q2 2026 report showed the sharpest quarterly decline since the pandemic, with the index dropping to 76.1 from 76.7 in the first quarter. That may sound small, but it keeps a downward trend going: the score was 78 back in 2024.

The complaint numbers really caught my attention. Complaints are at an all-time high, nearly doubling over the past decade. Earlier this year, ACSI reported a 16% surge in complaints in the first quarter alone. People aren’t just grumbling to themselves anymore. They’re taking the time to actually contact companies and say something is wrong.

It’s not the products; it’s what happens after

Here’s what surprised me. In ACSI’s 2026 study of appliances and electronics, product quality improved, yet overall satisfaction still fell because service and reliability eroded. The study drew on 21,590 completed surveys. One of its sharpest drops was in the simple act of getting help: the ease of arranging service fell 5%, and every manufacturer-provided service benchmark declined.

The researcher behind the study put it well. Companies often excel at designing products but struggle to support customers through years of ownership. In other words, we’re getting better gadgets and worse help when they stop working.

Is the robot the problem?

Many companies have answered the service squeeze by handing more of it to AI. It hasn’t gone well, at least not yet. A Qualtrics survey of more than 20,000 consumers across 14 countries found that nearly one in five people who used AI for customer service got no benefit, a failure rate almost four times higher than for AI use in general. Consumers ranked AI customer service among the worst applications for convenience, time savings, and usefulness.

I don’t think the technology is the villain here. The Qualtrics team diagnosed the problem as too many companies using AI to cut costs rather than solve problems. A chatbot that exists to keep you away from a human is a very different thing from one that actually fixes your issue.

Why companies should care

You might think bad service is just a cost of doing business. The data says it’s expensive. Nearly half of bad customer experiences (47%) lead to decreased spending. And the flip side is just as striking: consumers who choose a brand for great customer service report 92% satisfaction and 89% trust.

There’s a quieter problem too. About 30% of people with a bad experience tell no one. So for every complaint a company sees, plenty of unhappy customers are just quietly leaving, or planning to.

Trapped, not loyal

Here’s the uncomfortable twist. Falling satisfaction hasn’t yet produced a matching wave of people switching brands. The ACSI’s research director explained why: customers feel trapped by limited choices, since alternatives are often pricier or don’t exist. He also pointed to what’s feeding the anger: companies posting record profits while raising prices and delivering weaker service.

That’s not loyalty. That’s resignation, and resignation doesn’t last forever. ACSI’s founder warned that if this pent-up defection materializes, companies with high satisfaction and high retention stand to benefit most.

What would help

I’m not a customer service expert, just a customer, so take this with a grain of salt. The fixes don’t seem complicated:

Make it easy to reach a real person when the problem is real.
Measure whether the issue got solved, not whether the call got deflected.
Tell customers what happened to their feedback so speaking up feels worth it.

Good service used to be ordinary. Now it’s a competitive advantage, and it shows how far things have slipped. Companies that treat a frustrated customer like a person, not a ticket number, will stand out right now, and customers will notice.
