Online store is a disaster!

Ordered a cement mixer online a few days ago. Order accepted , paid for. No further updates Delivery date arrives si I decide to call Put on hold for over 12 minutes, twice. My Facebook message was eventually rep**** to and I was told there is no stock and dispatch should have contacted me ! I was waiting like an idiot for something that wasn't going to arrive , and after reading the reviews here, I'm nervous that my refund won't reflect in the 7 to 10 business days I was told. Thanks for nothing Leroy Merlin , 1st and last time I'll buy from you. Do you use your online store as a cash flow mechanism ? Why are we able to order and pay for stuff that isn't in stock ? Why is there no communication? Why do people wait months to get refunds ? You should be investigated as I can't see that anyone could be this *********** , it must be intentional.
