Hi Majid,
Sorry to hear the repair did not go better.
Did you fill out a parts checklist before you sent back your notebook?
You may want to continue working with ASUS support, but feel free to send me a PM at cl-Albert with your RMA number and any case numbers if you want me to look into it from my end.
Not sure if it would have been better to go back to xoticpc.com this time if they upgraded your unit, but you may also want to check with your store to to see if they can offer any help since they probably work with ASUS RMA as well.
Sincerely,
Albert
