Dawn Wing Courier delivered my parcel to the wrong address and wont take accountability

Dawn wing is saying that they have delivered , but in actual fact I have not received my parcel.

Their website says the parcel was apparently delivered on the 2nd Oct, but I haven't received it. They keep saying that someone by a certain name signed for the parcel, but there is no one by that name in my company.

I have been calling your Customer care number since the 2nd Oct until today, the 9th Oct , spoke to their Customer service agents and nobody has gotten back to me. Last thing they said they would do is to check with the driver where he delivered the parcel.

Dawn Wing has lost my parcel worth over R1000.00 and they don't want to take accountability for the loss or even give me decent update.
