Deteriorating Aramex service in South Africa: slower delivery and poor quality envelopes

I am very disappointed with the service of Aramex. In the past when I used them, deliveries were made within 24 hours between metropolitan areas. We were very happy with their service, it was great having an efficient reliable service. Unfortunately the last time, it took almost 48 hours for a delivery from Cape Town to the Vaal Triangle. The parcel left Cape Town at about 00h30 and was in transit for over 24 hours with no update on the website so we could inform our customers about where their parcel was. Trying to contact Aramex for an update is hopeless, their online agents cannot give any additional info about where parcels are in transit or when the delivery will be made other than within 48-72 hours. Also, the quality of the last sleeve/envelope was poor, just removing the tape to close it caused the sleeve to tear and I had to tape the sleeve shut. Very disappointing, I am going to have to find another way of transporting parcels over the festive season or I will be disappointing people like Aramex has disappointed me.
