Courier service that just can't be bothered to deliver

I made an online purchase from an international company and unfortunately they use Dawn WIng as the courier service. I have been in contact with Dawn Wing several times to try to track my parcel with no luck. The online track and trace is absolutely useless as is the service I have received over the telephone. I received an email saying my parcel would be delivered on the 17th September. No delivery was made. So I gave it a few days and then phoned Dawn Wing. I was asked to call problem parcels since apparently they had tried to call me. However, I had neither received calls nor any messages from Dawn Wing. So I call problem parcels and arrange for delivery on the afternoon of 27 September. Surprise! NO delivery is made. So I call again at 8.30 on 28 September. I received appalling service over the phone and was eventually told that the person dealing with my parcel would return my call. Two hours later I had still heard nothing. So I phone again. Once again I am asked to leave a message and will get a call back. I declined that offer and was finally put through to someone to assist me. This time I am told the courier tried to deliver but there was no one at home. That is absolutely NOT the truth. Someone was home all afternoon and evening. Plus they have to call my home through security at the gate and this did not happen ... which proves they never even arrived at my address. So once again I am told they would organise late delivery for me on 28 September between 6pm and 8pm. I agreed and ensured I was at home to receive it. Guess what! No delivery has taken place. It's after 8pm and I have still not received my parcel. What disgusting service! Here I sit and wait for absolutely nothing. It's a complete joke of a service. It appears Dawn Wing does not actually want to deliver my parcel. I plan on informing the international supplier I bought from that even though they sent my goods, the courier they use can't be bothered to deliver, and that I will no longer be able to make any future purchases from them since I really don't want to have to deal with Dawn Wing again. It would be nice to receive my parcel though, since I actually did want it.
