parcel damaged and now is lost

I couriered an A1 size painting on Monday 17th May 2021 through Postnet Edward street in Bellville. This parcel needed to be delivered in East London and it was wrapped with a 2m Bubble wrap and postnet cover sheet it also had ''fragile'' stickers all around it. I was told that it will be curried by Aramex because they work together with Postnet. I kept tracking my parcel online. When it got to East London the status reflected ''On hold - Incomplete address and that surprised me because the address was clearly stated on the waybill that it should be delivered to Postnet in Retail park Beacon Bay.

I called the destination Postnet office on this number +27 (43) ***. The lady I spoke to informed me that my parcel got damaged and I should expect a call from the sending office - Postnet Bellvile to inform me about the damage. Postnet -Bellville arranged for the parcel to be sent back to Cape town so that the damaged frame can be replaced. Firstly Aramex took two full to arrange for my parcel to be returned to Cape Town. Secondly, Yesterday 2021-06-01 I was told that the painting got lost in a Cape Town warehouse. I am very very disgusted with the service I received as it seems like no one wants to take responsibility for this. I cannot believe a company so big can be so negligence and unprofessional. I want my painting back and my money.
