Takealot Return Policy nightmare

So I bought a single CW3 camera from takealot. A few days later while trying to install it, I got a message on my app that says that the camera is already added to someone's profile and I can't add it to my profile. I also noticed that the screen protector was not there on this camera compared to the set that I had bought from Takealot previously. This clearly showed that someone installed this camera before and returned it. Noone at Takealot or their supplier ever looked at the condition of this camera and to check if it's been returned to a good condition for resale. They simply tried their luck to sale it to me. It's been 8 days now since returning the item, Takealot still says the item is still at their supplier for investigations but I have not gotten a replacement. I will have to wait for the said supplier to finish their process before I can get any joy. If takealot wants to replace traditional retail they need to have a customerfocused return policy that ensures that when they are at fault they speedily address the issue and make it right with their client. And not wait for an internal investigation, whilst customer is inconvinience and denied enjoyment of the product they have purchased with their hardearned money.
