NO DELIVERY & TRACKING NUMBER DOESN'T WORK

I'm disappointed that Aramex failed to deliver a very important pricey package. The package was dropped off at Pick 'n Pay Circular drive port elizabeth on 24 September 2018 and till today we haven't received it. The tracking number doesn't work and I've been calling Aramex since Tuesday 25 September 2018 and no one is helping nor willing to give me a concrete answer regarding the whereabouts of the package. What's worse is that i had to order another parcel as a replacement for the once we still haven't received which means spending more money. Instead of Aramex assisting in locating the parcel they keep insisting the sender is lying about sending the package...but why would anyone mess with their business like that, I mean sender used another courier service to send us the replacement package and it arrived the following day. I can only conclude that there's theft involved somewhere here. I'm disgusted by Aramex and its unprofessional staff that send you back and forth from one operator to another during a phone call, what's worse is one even hung up on me while the other raised her voice. I wouldn't advice anyone to use Aramex, it took money to buy that package... my hard earned money lost because of them. I'm disappointed and disgusted.
