Complaints and Feedback
The LNS is committed to excellence at all levels of customer experience. Complaints and customer feedback play a central role.
We want to know about real or potential issues, your daily challenges, hear what drives you most, and learn from your experiences.
Sharing your experience helps us stay in tune with how well we are meeting your needs, while also giving us guidance on how we can improve to provide you with an even better service.
We want to add value for you and help deliver the best care to our patients.
Feedback versus Complaint
Complaints and feedback are both valuable forms of communication, but they serve different purposes. When providing us with your insights, it is essential for us to diverse between your complaints and feedback to address your concerns effectively.
Below is a concise guide to assist you in distinguishing between the two:
Complaints
A complaint is an expression of dissatisfaction – related to its services, or the complaints handling process itself, where a response or resolution is explicitly or implicitly expected.
Examples :
- Late received test results
- Mistake in test report
Feedback (customer satisfaction)
Feedback (customer satisfaction) are opinions, comments and expressions of interest in a product, a service or a complaints-handling process.
Examples :
- Information of personal experience
- Suggestions on form, website, test
