Wal-Mart Can't Escape the Customer Service Doghouse

Wal-Mart has consistently earned a low opinion from consumers, but CEO Doug McMillon has vowed to improve the retailer's standing with customers. So how's that working out? Not great, at least not yet. The world's largest retailer slipped two points in the latest American Customer Satisfaction Index (ACSI), holding fast to its last-place ranking among department and discount stores. The survey is based on interviews with more than 9,000 customers in November and December.
