The Complaint Management System (CMS) is a simple Python-based application that allows users to add and manage customer complaints. It provides a basic interface for adding new complaints, managing existing complaints, and keeping track of complaint statuses.

• Add new complaints with details such as name, email, phone, complaint type, and message.
• View and manage existing complaints.
• Each complaint is assigned a unique complaint ID and has a status (opened/closed).
• The system records the date and time of each complaint submission.
• Data is stored in a JSON file for persistence.

• Python 3.x
