Their deliveries can take place at any time from around 8 am-5 pm. If you miss your delivery, you should receive a card through your letterbox to arrange a redelivery. If you have been waiting over 5 working days for UK delivery, please check with your local sorting office as they may be holding your package. If 15 working days have passed and you still have not received your items, please contact them and they will make contact with Royal Mail to resolve this.
