Bad service from Dawn Wing

Bad service and being **** to by Dawn Wing...I bought clothes online from Cotton On on the 25th November, I then got confirmation message on the 28th from Dawn Wing to say that they will be delivering my goods on the 29th November. Today the 29th November I received a message in the morning to say that I will receive my parcel by latest 18h30. Just after 15h00 I then received a message that my parcel couldn't be delivered as I was not home. I immediately called their offices to advise that I never left home for the day and that there was 3 other adults at home, I was assured that my query has been escalated and that I was going to received my parcel by 17h00. It is now 20h08 and I still have not received my parcel.
