Dawn Wings - Poor service delivery

I ordered wine from an estate and they shipped it using Dawn Wings.. I received an e mail with a tracking number and waited 4 days before trying to track the shipment. To my surprise the tracking report showed they had tried to deliver my wine on two consecutive days. I had received no notification that they were going to deliver on either day. I phoned Dawn Wings and after waiting for 15 minutes or so, was told I should have received a SMS confirming the delivery and an apology. I was advised it would be delivered on Sunday or Monday and would receive a SMS confirming if it would be a morning or afternoon delivery. On Monday 16th August I phoned Dawn Wings again around 10h30 as I had received no notification. I was told it was out for delivery but couldn't advise an approximate time. I asked if they could contact the driver and was told they couldn't contact the driver. I asked to speak to a supervisor or manager but was told they couldn't transfer the call. I requested that they ask the supervisor or Manager to call me in the next 30 minutes. Needless to say, I received no phone call at all. If you don't mind sitting at home all day for 3 or 4 days, then Dawn Wings is the courier to use. I won't be using them in future and anything I buy online, I will check which courier will be used and if it is Dawn Wings, I won't be ordering from that supplier.
