Bad service

I ordered something from an online store and I got an email from Dawn Wing saying it's been delivered yesterday the 29/11/17 at 9:40 am. I was home all day and didn't recieve anything... I tried calling Dawn Wing today to tell them that it's been delivered to the wrong address or something as I have not recieved anything and after like 3 calls I'm still waiting for them to call me back! I spend allot of money and I'm very very stressed out! I'm not even sure what to do next! Bad service... I never had these issues when I had a parcel delivered with fastway and the courier guy. Feels like I lost my money.
