Shipment theft

There was a shipment from abroad which was couriered with Sky Express Delivery Service. It arrived on the 16th February 2023 until today I didn't receive my shipment even after all required payments made. Worst scenario is that the company never responded to my emails nor my complaints meaning is what they do *****ing and ****ming people. Where is my shipment because I didn't receive it? This company is based in the Miami USA.
