Online purchase delay - absolute joke

I placed and paid for an order online on 6 Aug. It is now 20 Aug and my order is still reflecting as "Partial" and in preparation, with no communication from them whatsoever. I called in yesterday, was given no good reason for the delay and told that the order was escalated but i have seen no movement. We do these online orders because it is not safe to go into stores...but what it is the point of paying a delivery fee when you don't get the goods within the time frame advertised on their website?! Shocking service. I ordered well in advance knowing i would not run out of what i need if they delievered on time. But now i have almost run out. Leroy Merlin, please either deliver my order by this weekend or i just cancel, get my money back and buy what i absolutely need elsewhere. You really need to fix your online order system.
