This is the reply from Nikke team. What should I do for the next? How can I get my money back? thanks.

I translate it from Chinese to English for you better understand this situation.

“After further feedback and confirmation with the relevant team and staff, we understand that the Razer Gold channel does not support refunds at present, so it may not be able to process your refund needs for the time being”
 

Is there anybody can help me？This case is pending for long time，I can not do anything for that。
