Aramex Global Shopper has bad systems

After some really good experiences, service has now become really shoddy. I've had a Aramex Global Shopper account for years now, and recently spent money to upgrade my deliveries to FLEX membership. That was a waste of money because the service is now pathetic. The AGS site does not work: there are all kinds of issues with logging in, one cannot upload invoices when prompted to do so, queries on parcels are not responded to, the tracking is not up to date, and the list goes on. Calling Aramex is time consuming and your call often gets moved around and you eventually land up somewhere and your call is terminated without a resolution. I used their services for a while but since October it's really become a mess. Using their WhatsApp or Facebook messenger options also don't deliver any resolutions. My latest parcel was delivered in Shanghai on 25 November 2023. More than a week has passed and they still say they are waiting for an invoice, although this has been uploaded on the portal and there is no movement. Not sure where the issue is, but Aramex SA is not helping to resolve this.
