Missing item

Hi I ordered a few items on Takealot and in the parcel one time was not delivered at all and the other item was defective. I logged a return and the defective item was replaced. However the missing item was never sent again with takealot, and I am not getting replies from the takealot customer care. It is an item valued at R500 and I would like if they can either send me the item or issue me a refund Order number was MRRN-MVD6W-94OV
