IF YOU BUY SOMETHING OFF OF EBAY AND HEAR THEY ARE USING XDP, CANCEL YOUR ORDER IMMEDIATELY! Had shower tray delivered successfully by Screwfix couriers at 8:30am, they rang doorbell and called me. Easy peasy no issues....but when we come to a delivery by a different courier called.... XDP for wall panels, well they are just useless. They take a photo of the door claiming they attempted delivery. I was home all day waiting for this. They didnt ring doorbell or call me. Agreed to deliver again the following Friday instead. Now I'm notified they attempted on Monday and that they've tried to many time and will make no more attempts. Pathetic.
