Delayed Deliveries and Poor Service with Poor communication

We've got 3 Shipments that were done with Aramex through their drop off boxes at various outlets but it seems they aren't keeping their promises. I called the Silverton Branch today to tell them about the issues i'm facing, only to be told that they facing delays but also that they can't pick up one of my tracking numbers on their system. We dropped one parcel in Pretoria North on the 20th July 2020 destined for Lebowakgomo but that parcel to this day says that in transit (72hours later). We dropped off another one on the 22nd July 2020 at Pretoria North and this was addressed to Randburg, this parcel doesn't even show on their online tracking and they also can't trace it when i call them but the store says Aramex collected parcels on the same day. Aramex is making it difficult for us to do our business with our clients. You promised that parcels are delivered by 12pm the following day but you failing to maintain your own promise that even recited as we wait for our calls to get answered at your call center
