Leroy Merlin - Pathetic Customer Service

I ordered some items on 30th Nov to arrive well before Mid Dec as they were “in stock” . I called last week to query delivery you wait on line listening to the most dreadful music for ages then another 20mins while they try and get hold of the courier company . I have no idea whey such a large company uses a courier company like 1Time Express who do not even answer their phone!! I was told I would have my del “asap” I called again today and waited for 20mins only to be cut off. I cannot listen to that awful music again! The return and refund portal does not work. I just want my money back !!!
