Late delivery & lack of communication

I placed an order with Reebok on the 30/11/2019. Their normal estimated time for standard delivery is 3-5 working days but it was changed to 5 - 7 working days because of Black Friday. This means my parcel should arrive today. When I placed the order, there was no option for express or same day delivery - Reebok confirmed they deactivated this option as they would not be able to meet the deadlines. When I contacted the courier company (Dawn Wing) they confirmed it will only be delivered tomorrow. This is not good enough as the delivery date was already delayed & now they can't stick to this new timeline either. I called Reebok & they eventually confirmed they made arrangements with Dawn Wing to deliver by today. When I contacted Dawn Wing they advised they have no such arrangement or request from Reebok. Every time I try calling Reebok, I'm on hold for at least 10-15 minutes before being assisted. I have ordered from them before & that process was smooth with no hiccups.

I need this sorted today.
