Makro's negligence to its customers.

I bought 3 items for someone's birthday in May as they were on their birthday wishlist but when they were delivered I found out someone else already got those for his birthday. Had to return them, lodged a return and they were collected, still unused and sealed in original packaging since I never opened them. This was in May. After a month of waiting for my refund, they only refunded me for 2 items instead of 3 and they are claiming to have refunded me for all three. They do not answer my emails and their customer support is ***********. Bad service from Makro online, they do not want to give me the rest of my money and this has been ongoing from May, it is now almost mid August.
