Non delivery of paid order

Think twice before using Leroy Merlin's online platform. Whilst instore service of LM is better, their online service is nonexistent. I've bought and paid for curtains and a duvet cover on 13 Aug 2024. In 4 days' time it will be a monthly later without delivery, no updates, no comms, nothing from Leroy Merlin. Their site still show processing with no further updates. I've sent endless emails to request updates to no avail. I've given up on trying to get through on their support line. Please can someone give me an updated on my paid order ASAP or refund me urgently please. I will now also try to make contact and get an update via all social media platforms in an attempt to get closure on this matter.
