What is the Impact of Bad Customer Service Companies?
1. Increase in customer churn
Wouldn't you prefer ordering food from a place that delivers really fast and tries to resolve any problems simply and politely?
When the customer service team doesn't prioritize customer satisfaction, there is an increased possibility of customer churn.
2. Increased customer acquisition costs
Taking the same pizza ordering example as mentioned above, all customers who've ordered food from A would prefer going to a different pizza place. When companies face customer churn, it becomes difficult to acquire more customers. This is due to an increase in customer acquisition costs.
3. Decreased customer loyalty
A customer who likes the pizza made by A might decrease their frequency of ordering food when every customer service call becomes really difficult to find a solution. Such incidents can lead customers to become less loyal to a business.
4. Reduced customer satisfaction
When you look at all the aforementioned impacts, it becomes evident that the root cause is a decrease in customer satisfaction. When customers have repeated incidents of poor customer service, they become unhappy with how they're being served.
