Useless delivery

Ordered on Black Friday, delivery due on 11th do be delivered to my office before 5. Delivery guy arrived 17:41, no one available as offices closed at 5. On 12 December, reschedule delivery, I sat in car and waited till 6 at night. Delivery guy arrived 6:30, after I was promise he will phone me when close, no calls at all. Now on 13th December was promise to deliver before 12:00, well it is past 12, and still no delivery.

Won't see me using them again soon. Delivery is useless.
