Domino's Pizza

I ordered my food online at 11:40pm and it was confirmed that was placed, 2 minutes later my order was canceled per Dominos. So I tried to reorder my food at 11:48pm and 2 minutes later was order was cancelled per Dominos again. Per business hours, they are supposed to be open till 12 am. Another time, they called me around 11:30pm and told me that they were too busy to do my order. It’s ridiculous! Why will they put down their hours of operation till midnight if they would not make your order if you call after 11pm. It does not make sense and very unprofessional.
