No Delivery

I received a message on the 12/10/2017 telling me my parcel is out for delivery that day. I waited the entire day and it was not delivered by late afternoon I used the portal to request Dawn Wing to phone me. They did not phone me and I tried contacting the call centre and waited 15 minutes and could not get through to anyone. I then clicked the reschedule button for Friday . On Friday I got the exact same message and waited the entire day and they still did not deliver (I tried calling again to track my parcel but couldn't get through). Todat (16/10/2017) I received the same meesage and I still can't get through to anyone to assist and still have not been called back since I requested the initial request on the sms.
