Aramex Package lost

Aramex has lost a package that i have sent with them the pacakage contained health products that were not cheap, we have now called them over 5 times speaking to different consultants but still they have not given us any feedback. I use aramex to do all my shipments daily but from now this will change, i cannot understand how a package can go missing from a dropbox this service is terrible, and the worsr part is that they do not get back to you.
