Unreliable and worst online experience

I am appalled by the Leroy Merlin service I have received. First they do not deliver an order and cancel the order after it should have been delivered. Then they call to inform me about the cancellation and make a promise to pay me back the same day so I can buy the tock at a different place. I have received 8 email of the promised refund and cancelation but have not received the money. When I call them 4 days later to only tell me the person handling it did not initiate it on the system and it will take 10 days to get the money back. Then calling the duty manager I get told that I can go to a branch to get a voucher. Do es Leroy Merlin understand the concept of online shopping. Online shopping is for those that want to save the time to go out and collect what they need TO SAVE TIME AND MONEY. I ordered online products to be delivered. They did not deliver on their part and now they want to punish and inconvenience me more by asking me to SPEND THE TIME AND FUEL(MONEY) to go and collect the money they didn’t deliver on at a Leroy Merlin branch.
