Ebucks exchange

I purchased a Bose headphone on ebucks store site. i sent it in for a repair exchange under warranty. the process took 1 month. it seems it was not Bose south africas fault because their turn around time was 24 hrs. ebucks and dawn wing couriers took just about 30 days to collect and send the item to Bose in JHB and return it to me. today i received a **** chinese no name headphone not from bose. ebucks has no management for the return process. i havent spoken to anyone of authority to solve my problem for this entire period. service is worst i have ever experienced.
