False delivery dates

I placed an order and received a delivery date. On the date of delivery, my order status still has processing. I contacted their customer service whom stated the order is still at the warehouse and they are unable to assist until it reaches their branch. There's now a new delivery date which is more that their 2-4 working days. I need my order for a trip and it will now be ready for delivery on the day of departure. I still can't cancel the order as there's no communication to their warehouse. Returns with be another inconvenience. All customer service said is 'sorry' it's an estimated date. There's also no option on the app for express delivery. Really poor service considering you are offering an online service which makes delivery your most important service/perk!!!!
