Returns process flawed

The first time I returned an electronics item to Takealot and now they say I damaged the products. I took it out of the box and was not happy with the product and packed it back in all the original packaging. I returned it to the Bellville branch where they just scanned it and shipped it to Montague Gardens for inspection. Why don't they inspect it in front of the customers. How can they prove that the item was not damaged during transport to Montague Gardens. All they did is inspect the item at Montague Gardens WHS and closed the returns ticket without notifying me. It has now been 12 days and the issue is still not resolved nor has the items been returned. There is no proof that the same serial number I received was inspected and damaged.
