Thanks. My problem was I didn't know which carrier they use in UK. However I discovered Dell Customer Care who were very helpful and have raised a ticket to alter the delivery date for me. Just awaiting confirmation.
My delivery date has changed from 12/5/2022 to 16/5/2022. I will not be available to receive until 19/5/2022. What will happen to the package. I cannot find anywhere to change the delivery date.
Delivery date change - What happens if i am not available
