I called them yesterday and he said they submitted the credit on 11/30 and it should show up in 7 business days in my statement. Today is day 7 and I don't see any activity yet.
I'll call back again on Friday if I still see nothing.
mine was delivered on 28th november and charged the same day as well (ordered 13th nov.) no credit yet, but i do see a 1.00 pending transaction from google dated 12/10. hope that will be the credit. not sure though. will keep you posted
