This issue is happen to me. Stupid proton still promoting this rebate even they dont have stock anymore. I see a lot of complain at Proton FB.
All customer that entitled this rebate have this issue. i already complain with proton, my car is arrive this january. but the rebate status unknown. My SA said the rebat will automatically cancel on january. Feel like being scammed.
i thought u already change SA?
The solution is wait for the 2015 version. U already pay high deposit.

i have book mine 3 weeks ago. Loan also approved. After loan approved, my SA said there is no stock anymore.
Yes, there is no white in stock anymore. 

i always liase with my SA about my car. also ask about the january promotion. My SA said proton still waiting their CEO approval for new year promotion. Maybe need to wait until next week.
