When I ordered the blind I was told it would delivered on 29th April. We then received an email apologising that it was delayed until 30th. We couldn’t open the tracking until deliver date we were told. Someone tried to deliver it on the 25th. We were in all day but never heard the bell or a knock. We got a card through the door about a missed delivery but no indication of what was attempted to be delivered. We reasonably assumed it wasn’t the blind. When the tracking was available we found it was the blind. But the tracking stopped there! We’ve rearranged for it to be delivered today but no tracking or indication of delivery time. It’s now with Royal Mail we think - hopeless. Terrible service. Total disregard for customers made worse by incorrect and misleading info. You need to find a reliable delivery system. Velux generally - excellent products
