I can offer some general guidance on how you can address your concerns: Gather evidence: Collect all relevant documents, emails, receipts, or any other evidence that supports your claim of being cheated. Having proper documentation can strengthen your case when seeking a refund or compensation. Contact customer support: Reach out to the customer support departments of both Byju's and Goibibo. Explain your situation, provide details of your complaint, and request a refund and compensation. Be clear, concise, and polite in your communication. Keep a record of all correspondence with the companies. Escalate the issue: If you do not receive a satisfactory response from customer support, consider escalating your complaint. Check if both companies have a dedicated escalation process or a higher-level department to handle such cases. Follow the designated procedure to raise your concern to a higher authority within the companies. Consumer forums: If your efforts with the companies do not yield results, you may explore filing a complaint with consumer forums or regulatory bodies relevant to your jurisdiction. These organizations are designed to handle consumer grievances and can provide guidance on how to proceed with your complaint. Legal advice: If the amount involved or the complexity of the issue warrants it, you may seek legal advice from a qualified lawyer specializing in consumer rights or contract law. They can assess the specifics of your case, provide legal guidance, and help determine the best course of action. Remember, the specific steps you need to take may vary depending on your jurisdiction and the applicable laws. It is important to consult with a legal professional or consumer rights organization familiar with the laws and regulations in your area for personalized advice.
