This is the WORST service I have ever had in my life!!! 13 days of fighting and still we are outstanding items!!!!

My mother went to Leroy Merlin Boksburg on the 30th December 2023. she bought R80 000.00 worth of tiles and items from their store, for these items to be delivered they charged her R2 800.00 with an estimated delivery day of the 31st December or 2nd January. On the 2nd she had to call in to find out what time my delivery will be as she had no communication from the store, they then told her that the delivery will be there on the 3rd. The same thing happened on the 3rd and 4th, she eventually got my delivery on the 6th. However they didn't deliver all of the ordered items and a lot of the tiles where broken. She called the store to inform them of these issues they asked her to send an email with all the details so they can sort it out, this pattern repeated every day. I started calling them on the 9th because she wasn't getting any feedback, no delivery happened that day and I had to call back on the 10th. on the 11th I then lost it on the phone with them and insisted to talk to a manager the manager then promised me a delivery on the 12th. On the 12th they again delivered broken tiles and all my items still didn't arrive. the managers stopped taking my calls and the call center kept giving me different stories. On the 13th I had enough of their stories and told them to cancel all the outstanding items as ill buy them from fourways. I went online and ordered the tiles for instore pick up as the system told me that boksburg had stock, imagine my surprise to find out they have 11 boxes in stock when I called the store to confirm for pick up on the 14th However when I arrived to pick the manager informed me they have no stock and that id have to come back in 7-14 days. After I had a meltdown in store the manager promised me that he will arrange with Fourways to deliver to me on the 15th free of charge. I'm still waiting for my tiles and the manager is now saying its out of his hands as fourways needs to deliver. the entire time the team kept blaming other departments/people instead of sorting out my problem.
