A. 1. Document your complaint: Keep a detailed record of your complaint, including dates, times, and the names of representatives you spoke with. This can help you escalate the issue if necessary. 2. Use multiple channels: If your complaint is not being handled adequately through one channel, try reaching out through different methods (app, social media, email) to ensure it gets attention. 3. Be persistent: If you feel your complaint is not being addressed, continue to follow up until you receive a satisfactory response. 4. Seek escalation: If possible, ask to speak with a supervisor or a higher-level representative who may have more authority to resolve your issue.
