Clicks service and merchandising

Website shows you have item in stock. I ordered it using Ebucks, a few hours went by and then I get a message saying no stock, money will be out into my clicks account. If you don't have stock why don't you update your site and not take orders ? Also the biggest concern is refund through my methods of purchase. This is a huge inconvenience to me now to get it refunded the way I want and your team's are saying I must wait for 48 hrs before I can even ask for that process to be done. Until these two things change I will never be purchasing online from clicks.
