Goods for delivery are not a priority

I purchased a bed from HiFi Corp. Woodmead on the 05/04/2015 and requested delivery for the following Saturday as I work during the week and I live alone. On Saturday I waited the entire day at home and made numerous calls to HiFi Corp. were I was told it may come, wait until 6pm and if not it may come on Monday or Tuesday. This is a pathetic attitude to have however I patiently waited as I already paid. Today being the 13/04/2015 I have not received the bed still and I have not been contacted in anyway to apologize for the inconvenience, yet when the sale was made I was assured numerous times so that payment would be made. I would like to know firstly when will I be contacted and appologised to for this pathetic service and secondly when will the bed arrive and if I actually will get a time that is convenient to me? Also I would like to know that someone is going to look into this matter and insure future customers are not put through such hassles after paying for goods!
