Worst online shopping experience ever!!!!!

On Tuesday the 1st of December I ordered 3 items from @home online store. Knewing how urgently I needed the items I requested for express delivery. Order went through, and then later that day I was told I ordered a flammable item and therefore they won't be able to do express delivery. The email went further to say my items will go through the standard delivery process which might take 3-5 working days. I explained to about 5 different call center agents that I needed the gifts before or on Friday the 4th. Long story short, on Friday I was advised that my order will be delivered. I have been waiting here like an idiot, needed the items today because they are gifts. This is possibly the first and last time I shop with @home online. What kind of sick service is this? I should have been told whilst I was busy with the order that one of the items is flammable and therefore... I was not even given a choice to either remove the flammable item and still get the things on express delivery...I was just told I can't make any changes to the order. Now I have to buy new gifts all thanks to your incompetency. Keep the parcel , I don't need it anymore but I want my money back!!!
