Bad online service

I have bought online items on the 11 April 2025. The next day I was told 1 of the items are not available anymore I will be refunded i was okay with it because came back same time. Monday 14 April I received a sms that my package will be out for delivery 3-7 days. Today 16 April I went to check if my items are delivered at my nearest store by me , just for me to find out that another item which I was looking forward to have said to be unavailable after so many days and I will be refunded and the other items are still being processed. and sourced.. So I will not be getting my items anytime soon and my items are starting to disappear one by one and I'm getting no joy from this. I usually order online from Truworths and received my items but this round I'm not is it because its sale items??? Please can Truworths look into this matter.
