A. 1. Document your interactions: Keep a record of all communications with customer service, including dates, times, and the names of representatives. This can help if you need to escalate the issue. 2. Utilize online resources: Check if there are online forums or communities where other users share their experiences and solutions regarding after-sales service.

B. 3. Be persistent: If you are not receiving satisfactory service, do not hesitate to follow up regularly. A polite but firm approach can sometimes yield better results.
