Giant Gaming Deluxe Sound Beanbag

I would like to review but bought this 6 weeks ago from Argos and still don't have everything, the Giant Gaming Deluxe Sound beanbag has arrived but nothing else i.e plug, connections, instructions. We have had 4 deliveries and not one has had the full set in, they are all just pure bean bags and nothing else. We are now at the stage where they are out of stock and we are still waiting and fingers crossed it is in time for my son's birthday.
