Online advertising of products not in stock!

Very unhappy with the online order system. Money out of my account and I have nothing to show for it. Story goes: placed an order for two 2000w graphite Mellerware fan heaters on 23 July 2021. Expected delivery date to the Boksburg branch was 2 August 2021. I've been following up on order number *** ever since with absolutely no satisfactory outcome. Leroy Merlin does not return calls and advertise stock that they don't even have in store. Be warned! If you can't find the stock by visiting the store in person, don't use their online system as you will not get what you ordered!
