Incredibly poor service and lack of customer care

I made an order, online shop kept on clearing my cart and eventually I paid for an incorrect item, I immediately sent an email notifying them of the error and asking that the change my product before processing my order. I was requesting a different product with the same amount. The order was made at 01:02, the correction email was sent at 01:09 and the order was only processed at 08:23. I never received a reply to my email, instead they send me the ordered products. When I contacted them again via email about it, Bev simply said they cannot assist due to their processes. She did not as much acknowledge that my email was not attended to or had they done so, they would have been able to fix the mistake on time as the order was only collected at 19:34. The company does not provide contact number for consumers to reach them timeously. Instead Bev told me that they received hundreds of orders and emails everyday, insinuating that they could not be bothered to attend to my single email about my order. The response was dismissive and indicated a lack of care for customer service and experience. I am truly disappointed in the manner which Bec handled my request and I asked her to escalate my case to which she stopped replying to my emails. This is truly poor and unexpected service from a brand that supposedly advocates for the wellbeing of woman. It seemed as if I am not important enough after having spent my money
