I filed the support ticket while the support guy kept asking me turn to Turbine for help(FYI I do asked them and they replied that i should ask steam for the missing CD-Key).

I quoted the response from Turbine guys in my supporting ticket, and got following response: "We have provided all the available information and will be unable to assist you further with this issue. If you have an unrelated problem, we will be happy to assist you. If you would like a refund for the title, please let us know."

Hopefully find someone from steam i can appeal for help..
