Abysmal customer experience failure

I have been attempting to place my order via your website for 2 days now. I only shop online and as such have extensive experience with bit app and website-based digital platforms. The Dischem website is not only slow due to the image size and inefficient layout and format but lacks an adequate search function, making the user experience beyond frustrating. Items are miscategorized and misspelt, for example, Shower to Shower Powder fresh deodorant is listed as Power fresh (‘d’ missing), making it impossible to find in a search.

After adding all of my items to the cart upon check out I selected the option to utilise my Benefit rewards, which were duly deducted and app****. When checking out and choosing a payment option I received an error message saying that Something has gone wrong, try again later. After trying again several times during the evening my cart was emptied and I had to start again. After repeating the entire process of selecting and adding y items back to the cart, an =d proceeding to check out again I received the error message that I do not have an active cart and that something went wrong. I have tried for 2 days to check out and am in complete disbelief that a multinational corporate such as Dischem would have such an inefficient online platform that has caused me hours of frustration. The fact that it’s impossible to check out means that I have no choice but to change to Clicks and order from them as I am not willing to drive to a store because your online platforms malfunctioning website that is clearly designed and maintained by ***********, inefficient staff who have clearly never engaged in user experience testing to understand how woefully inadequate it is. To add insult to injury your customer helpline is not even available on a Saturday so you need to specify that online order should only be attempted during office hours during the week as no support is available over weekend. What a disgusting experience.
