Takealot not adhering to their 6 month return policy - no reason given by Busisiwe N for rejecting my claim

Takealot have such a HORRIBLE return policy. I bought a DStv standalone decoder in June, in September it said decoder may be ******* and then went blank, there was not power interruption whatsoever, I logged a return on their app, they came and took the decoder while I was at work (they only took the decoder and left the power cable, hdmi cable and remote). Almost a week later I receive an email from Busisiwe N saying that they reject my return request and that I should call Multichoice, I was not given any reason whatsoever on why my claim was rejected and to make matters worse, they attached pictures of the decoder, just the decoder and nothing significant and this shows the incompetence of the person who was just following a procedure without understanding what pictures should show. Takealot has a 6 month return policy for defective product. The decoder went blank (tried it for 2 days and trying to reboost), that is not a signal related error code hence the advice to call multichoice is an insult to me as a customer. Disgusting service!
