Worst online shopping expierience ever!

I do most of my shopping online with various companies, with no issues. I also successfully run multiple ecommerce stores myself, so am very fami**** with the processes related to online shopping.

I placed an order with Leroy Merlin for the fist time on 28 July 2021, and it most definitely will be the last time that I ever place an online order with them! After numerous calls, I was informed that some of the items were out of stock, despite is showing as in stock on their website - however I know that this sometimes happens, so accepted it. The Edenvale branch then got more stock from another branch and the parcel was finally handed off to their courier company on 6 August 2021 - according to an email that I received from Leroy Merlin, which states that delivery will be in 3-5 business days.

It is now 7 days later and the parcel still has not been delivered! I was promised that I will receive an sms from the courier company, this never happened. I've emailed, and received no reply. I've also been calling them daily this week and was promised delivery on either 11 or 12 August which never happened. Yesterday I was promised that the courier company will call me, this never happened. I requested a tracking number repeatedly for 3 days, and was finally given the tracking number today. I was then also promised today that they will contact the courier company via email and copy me in on this email - this never happened either.

I then tried to find the website of the courier company (Nucleus Couriers), so that I can at least try and contact the courier company directly or at the very least be able to track the parcel. Of course the web address given to me by Leroy Merlin staff http://nucleus.co.za, was also incorrect, but I managed to track them down by myself. Their phone number is ***. I called them today, only to be informed that the parcel is apparently damaged, plus to inform me the Leroy Merlin did NOT hand the parcel over to them on the 6th August, and that they only handed the parcel over on the 11th August, meaning Leroy Merlin **** about the shipment date! So I now once again called Leroy Merlin and the lady said that she will investigate and call me back - let's see if this is actually going to happen....

Suffice to say, in all my years of doing online shopping, this has been the absolute worst experience ever and I most certainly would never order from them again!
