Disappointed with Dawn Wing

I ordered an item via a website the delivery company is Dawn Wing. I called Dawn Wing yesterday to investigate as to why my parcel has still not been delivered. After numerous calls they ensured me that the parcel will be delivered lastnight being the 22 Dec between 18h00 - 22h00, I requested them to rather deliver between 21h00 - 22h00 to ensure that I would be home. I stayed up lastnight unitl 23h00 hoping that they would still deliver, which they didnt, not even a telephone to explain why they would not be delivering. Also, no apology this morning as to why they didnt pitch lastnight. I called Dawn Wing this morning just after 09h00 - I have been shunted from pillar to post for 18:17 minutes - wanting to speak to any manager - but unfortunately there isn't one manager available - this is one of the busiest times for Dawn Wing - how can there not be a manager to take my call. I am extremely disappointed with the service that I received during this critical period.
