Unreliable, terrible service

I placed an order on 9 Oct. On 12 Oct I received a message that my items will not be delivered. I then sent this message in the morning ORDER # ********** 53 I need this delivered to me today, I received a message that it will only be delivered on Monday.Please can you make a plan, I especially bought them early so that I would get them today. I have booked a photo shoot for my boys for tomorrow morning and I will not have a chance today to go and buy them clothes. I was then told that it will be delivered. It has still not arrived, so I sent another message now. To be told it won't be delivered today. What am I supposed to do at 5pm in the evening!
