Continued bad service with dishonest communication

Continued bad service and lies from Aramex. Amazon mainly uses them to deliver their parcels to South Africa. Unfortunately, Aramex's service is extremely bad. They will indicate that delivery will take place (for which I then make arrangement to ensure someone is home to receive the parcel). The problem is then that the courier is not capable to do their actual job and deliver the parcels as scheduled for the day, meaning I have to make the same arrangement again the next day when they will then hopefully deliver. To make things worse - they then outright lie on the website to say that they attempted delivery (which they DFINITELY did not). That, in my mind, is dishonest and unprofessional. I've raised this with them a couple of times already, but they really don't care and nothing changes!!! I then also had issues with parcels being lost, someone else's parcel being delivered at my home and they then having to look for my parcel (and further delay delivery), parcels being directed to the wrong country and this week they actually delivered an empty open envelop with the item missing (how they did not see that, I will never know)!!! You then also get very little support if you try and phone their customer support. Where I have a choice, I try not to use them anymore.
