Online sale is **** they deliberately remove clothes then after the sale those items appear again

If I could give them 0 star I would cause am tired really. Please be careful when buying their online sale. Truworths is advertising clothes then they remove them from their online store once you purchase. I noticed kn their 50% sale some clothing items disappear once you purchase then when the 50% sale is over if you go back on their website those clothes will appear but only the price has gone up. I have tried to buy joggers and tops on 2 seperate occassions they actually take money from my account then following day the tops are no longer available. I will prove this by Monday 2 september 2024 as soon as the 50% is over. As is I am still waiting for my refund from my first purchase because they will still deliver jogger pants without the tops so what am supposed to do with them because these are supposed to be sets. Please just refund me my money back and dont bother sending me pants because I do not want to go through the process of returning in store.
