Wheelchair accessability - Consumer Complaint for Clicks Store - Head Office

I have, on numerous occasions, complained to management at the Clicks branch at Horizon Village that I cannot move around in my wheelchair in the shop because the beginning and end of the isles are packed with displays and are also way to close to the dispensary division. I cannot get around in the shop without bumping things off and in places I can't even get to an isle. I've complained about this to management who have an absolute don't care attitude. They say that they can't do anything about the situation because the head office tells them how to arrange the the isles and displays. PLEASE SORT THIS PROBLEM OUT. There are many more wheelchair bound people that can't shop in that branch because it is NOT WHEELCHAIR FRIENDLY.
