Very very bad service

I purchased items 3 days ago and was asked to pay a extra amount for next day service and delivery, it's day 3 and still nothing, I even went on there help line and asked them what's wrong and how much money they have already made from other people because I have now proof of this they don't let you no and they lie with there promise oneone has come back to me so far so I don't think there is anyone working there or am I wrong?
