A. If you are unable to open a dispute, ensure that you are within the dispute period, which is typically 15 days after the order is marked as completed. If you are within this timeframe, navigate to 'My Orders', select the order in question, and look for the 'Open Dispute' button. Follow the prompts to submit your dispute.
B. If the button is not available, try clearing your browser cache or using a different browser. Sometimes, technical glitches can prevent options from appearing. If the issue persists, consider using the mobile app to see if the dispute option is available there.
