What four major reasons why customers get upset?

Customers often get upset for several key reasons:

1. Poor Service: Lack of responsiveness, unhelpful staff, or long wait times can frustrate customers.
2. Product Issues: Defective, damaged, or not as described products lead to dissatisfaction.
3. Unmet Expectations: When products or services don’t deliver on promises or advertised benefits, customers feel let down.
4. Pricing Discrepancies: Unexpected charges, hidden fees, or perceived unfair pricing can also trigger frustration.
