Some patterns really jump out when comparing how companies manage complaints. In a breakdown of best and worst customer service, names like Hulu, HBO Max, and Wayfair earned praise for quick response times and trained teams that actually solve problems. They tend to use centralized support and offer chat or phone help without pushing people in circles. Meanwhile, brands like Credit Karma and Groupon struggled with basic follow-up, often ranking low due to unresolved issues and vague communication. What sets the better ones apart is consistency — not just tech, but people who know how to use it.
