Shocking service and delay in delivery

I ordered an umbrella on Monday 18 November and was told it would be delivered on 21/22 November. I received a message on 22 November stating my delivery will be arriving but no one showed up. I phoned Leroy Merlin to find out only to be told they will follow up with courier and phone me back, no one phoned me back. Today, 25 November I again phoned to follow up but have received absolutely zero assistance other than an email confirming my ticket. TERRIBLE SERVICE!!!!!
