Pathetic returns service from Incredible

I am currently bedridden from a foot injury and am going in for surgery with a lengthy healing time. I wanted to order an over-the bed desk in order that I can work comfortably from my bed. I placed an order online with Incredible, and received the wrong product. I immediately started the returns process, and have been waiting a week for any response. Now after phoning in I find out that they are out of stock of the item and I have to wait another 2-3 weeks for a refund! Most pathetic service from Incredible and I will never buy from them again and neither will any of my family....FYI my ref no is ***
