Unacceptable service

I ordered a fridge from Home Hyper City on 26 Jan 2021 because my present LG fridges has cooling problems which I am not prepared to spend any more money on. I ordered a Defy from Home Hyper City because I was under the impression that it would be delivered within 2-5 day as per their website. After I made the payment it turns out there is no stock and no firm delivery date could be given. I also distinctly selected shipping to my address and the webpage order indicated free shipping. According to Home Hyper City I would collect myself. Now there are costs additional to the price I based my buy decision on. I really think this is misleading. Furthermore, stock levels should be indicated on the website so the buyer can make an informed decision BEFORE paying the supplier.
