Makro ***********, doesn't want to give my refund

Pathetic customer service from Makro, there's was an issue were the courier company delivered my goods to another address and Makro acknowledges it but for over 2 months their accounts department can't keep saying they're working in the problem...how *********** are the staff at Makro...I must now beg for my refund and keep getting told the matter is getting resolved. How long does it take to give a refund? This thieving company doesn't seem to care about customers...I will definitely not purchase from Makro online ever again, such a useless service.
