The Edgars Website is the worst online shopping website I have ever used

The Edgars website is SUPER slow when navigating pages. A new page takes forever to load. Searching the website is slow, navigating between the different results pages is slow, waiting for the page to open when clicking on a search result item is slow and it is slow when returning to the previous results page. It's slow when adding items to my cart and removing items from the cart. Worse than even this, is the webpage where I need to select a delivery store, it has a mind of it's own. I wanted to select Kenilworth Center as my delivery store but I ca never do this because whenever I scroll down the list, the page just closes down. I have tried 30 times now and every time I cannot select my delivery store. This is truly the wort of all, Makro, Loot, takealot and so many other online webstores just work but Edgars can't even make a working website. Tried on Firefox and IE and it is not my internet connection because all other websites work fine. I have complained to Edgars and they have not cared to respond because they don't give a damn.
