From incorrect deliveries and prolonged complaints to inaccurate order-taking systems and changes in policies and support models, each case highlights a different type of issue in the service delivery process.
The common thread is that decisions related to technology, operations, or policies can directly affect customer satisfaction, trust, and their willingness to remain loyal to a brand.
In this edition, Viettel Customer Service reviews five cases from Amazon Prime Air, FedEx, McDonald’s, Southwest Airlines, and Klarna to examine the causes, impacts, and CX lessons from each situation.
Amazon Prime Air – High-Tech Delivery Experience Ends with a Package in the Swimming Pool

Recently, a customer in Texas named Lindsey Austen placed her first order through Prime Air and was looking forward to experiencing Amazon’s drone delivery service. However, instead of dropping the package at the appropriate delivery location, the drone dropped it directly into the swimming pool behind her house.
The incident did not cause any injuries or damage to the drone, but it highlighted a clear customer experience issue: technology may perform well throughout most of the journey, but a single mistake at the final touchpoint can turn the entire experience into a negative one.
CX Lesson: Technology only creates real value when the end result is accurate and reliable. Companies need to have a fast and clear recovery process in place when something goes wrong, so customers do not have to bear the consequences themselves.
FedEx – Customers Struggle to Reach Human Support in “Chatbot Hell”

Recently, WIRED journalist Dillon Thompson shared his experience after purchasing an e-bike worth nearly $2,000. FedEx notified him that the package had been delivered and signed for, but in reality, he never received the bike.
For nearly three months, Thompson repeatedly tried to resolve the issue with FedEx, the bike retailer, his bank, his credit card provider, and local police. However, he was frequently routed through chatbots and different support systems, while finding it difficult to reach someone with the authority to actually resolve the problem. Thompson described the experience as “Chatbot Hell.” Ultimately, the bike was never found, and he said he lost approximately $1,700.
CX Lesson: A service failure can become much more serious when customers have to find the person responsible for resolving it on their own. Companies need clear ownership and escalation mechanisms that allow customers to reach a human agent when an issue goes beyond the capabilities of automated support systems.
McDonald’s – 85% Accuracy Can Still Be Not Enough for CX

McDonald’s previously tested a voice-based ordering system at more than 100 restaurants in the U.S., with the goal of reducing service times at drive-thrus. However, during real-world use, many customers began posting videos showing the system misunderstanding requests, adding items that had not been ordered, or creating orders that were completely different from what customers had requested.
Some incidents went viral, including cases where the system repeatedly added large quantities of Chicken McNuggets to an order. Although McDonald’s had stated that the system achieved approximately 85% accuracy, the company later decided to end the trial with IBM.
CX Lesson: At direct, high-frequency customer touchpoints, “almost right” may not be good enough. What matters to customers is not the average accuracy rate, but whether they receive exactly what they asked for.
Southwest Airlines – Loyalty Points Are No Longer the Only Reason Customers Stay Loyal

Recently, Andy Locke, a longtime Southwest customer, shared that he previously rarely considered other airlines because Southwest offered a simple and flexible experience, along with a policy of allowing two free checked bags.
However, as the airline introduced assigned seating, changed its boarding process, added paid priority options, and ended its policy of two free checked bags, he argued that while the Rapid Rewards loyalty program remains, some of the benefits that previously made customers want to earn points and continue choosing Southwest are gradually disappearing.
CX Lesson: A loyalty program cannot compensate for an experience that is losing its value. When the benefits that once differentiated a brand are removed, customers have fewer reasons to remain loyal.
Klarna – AI Can Reduce Workload, but Customer Support Needs Balance

Klarna has previously announced several positive results from its AI customer service assistant, including shorter resolution times and a significant reduction in workload for its support team.
However, CEO Sebastian Siemiatkowski later acknowledged that an excessive focus on cost had led to lower support quality. Klarna subsequently adjusted its operating model, strengthened the role of human agents, and ensured that customers could still reach a real person when needed.
CX Lesson: Operational efficiency should not come at the expense of support quality. For complex issues, customers still need fast and easy access to human agents who have the ability to resolve the problem from beginning to end.
