First time customer totally disappointed

I am a first time customer who had ordered gifts for my son's 2nd birthday. I do admit I had to try and return products before it arrived as I had to leave town suddenly for work and I had been notified that it could not be and would be rescheduled which was fine. Yesterday the 20 November I decided to track my order with the website saying delivery will take place by 16:00 PM however this was not the case. Countless mails and phone calls back and forth and no answers meant I had to go home on my son's birthday empty handed. I had even contacted skynet as I had been told this was the 3rd party courier doing the delivery. This company did not have any details either. It is now the 21st and still nothing. The website has not even been updated. I have called the call centre again who is now telling me that the stand procedure when delivery has been rescheduled and sent back to the warehouse is that you need to reorder. I have never been told of this. Even if that were to be the case i dont understand how the website can say something different and that my order is going to be delivered. I am very very dissatisfied. My son was heartbroken . Please fix this .
