I apologize for the issues you had with your laptop. I am also sorry for the experience you had with customer support.
You notebook comes with a manufacturer's warranty from Asus that should be good for 2 years after the purchase date. Under the warranty repair terms, you should not be charged for any repairs unless it was customer induced damage (physical damage). Which company processed this return for you to us? Back-up disc can be made free of charge using a utility that came with the Asus laptop. Every Asus laptop has a hidden recovery partition in the C drive. There is a back-up utility that comes preloaded with your machine. You can use this utility to make your own back-up discs instead of paying $50 for them.
If you have any issues, questions or concerns about your Asus products, please feel free to reach out to me at email@example.com. I'll be happy to address and questions or concerns that you might have.
