Myrunway running away from their mistakes

So on 21 February 2024 I buy a few premium brand items which was marked down, and I'm really happy with my purchase, because the sizes I wanted was available for a change. my money left my account and I received my order confirmation and invoice via email...estimated delivery normally up to 5 working days. after 5days I check what is happening to my order and see that order has been closed and refund is in process. I called their call center, and was told that due to routine maintenance the wrong pricing was loaded and that customers were informed on 22 February 2024...I never received that information ...I was also pointed to their terms and conditions which allows runway sale which reserves the right to cancel any sale concluded...where is the consumer right in this instance? I requested to speak to a manager regarding this... I was promised that the manager will call me...no phone call up this point. I'm utterly disappointed in how they treat their "valued" customers.. I guess I'm deleting my runway app.
