Wrong sizes 3 times delivery and returns Charged

i bought an item from Takealot asked for a specific size and on 3 occasions they sent me the wrong sizes i asked for Small and got Medium, Large, XXL and so on, i returned the item 3 times and got charged delivery and return fee which is not satisfactory as it is not my fault if they cant send the right item i now gave up told them to give me a credit and got charged for send the item back., i want what i paid for it which is R180 and 3 times delivery and return charges which i paid. i have always been happy with takealot but this time i am really disappointed in their service and will think twice before ordering from them again, they just money making on delivery and return which is not our fault.
