Bad service at Aramax

I've been using Aramax for more than a year, but lately they've turned out to give very bad service. I've phoned the Sandton office on more than one occasion, and yet people are still waiting for their parcels for nearly a week. If you send to an address more than 50km from the main centre (this info is of course inside the bag once you've bought it), they hand it over to an AGENT, but it doesn't seem as if anyone checks up on the performance of the agent. They are also supposed to be affiliated with Postnet - yet Postnet refused to accept a bag from me at Brackenfell, and Aramax just took it back to their office in Cape Town, without contacting me, or the client to get an alternative delivery address. They advertise overnight delivery, but oh boy - nothing is further from the truth. And no e-mail address to complain to, or Head Office. Another thing is that as soon as the person at their switchboard hears you are upset, he/she promises to put you through to someone to help, and then leaves you.... on a cellphone..... eating up your airtime.... to listen to their adverts....until you hang up and try again. NOT ON!!!!
