Pathetic customer service!!

This is a pathetic store to ever shop at, i made an online order on 24th of december and received an email on the 27th stating that my order has been processed to the newcastle branch and will be contacted for collection. I had to call in at the store and was told there's no order placed for the chairs i paid for!! spoke to the staff named Zuzile who referred me to the store manager Charlote(3rd January 2024)who also was very unapologetic about this incovenience and made it clear that its not their problem. Fine I was promised the Picasso chairs will be ordered and i can collect on the 27th as that was the only date i could drive to Majuba mall from Dundee! Again today(25/01/2024) I had to ask Zuzile why havent i heard anything from the store. she told me she will check and come back to me, hours later im told there's no chairs!! i asked for the store manager again to contact me. Charlotte phoned and confirmed there is no chairs they still making them from the Warehouse!! I mean i had no feedback from the store after 3 weeks im told there nothing they can do its not their fault!! how can House & home advertise something, allow you to make a payment!! promised that the order has been processed and can be collected from Newcastle when the chairs are now only being made!! Im fuming as i type this cause this is totally uncalled for!! pathetic store, people should know there's no value for your money in House& home!!
