Subpar delivery service and poor customer communication

Dear FedEx, normally I'm a huge fan of the service you provide and have never previously been disappointed by overseas shipments that have been handled by your company. Unfortunatately this no longer holds true as my current shipment has been a true nightmare as of today yet unresolved.

I ordered a small shipment in the US that was shipped on the 29th of July 2019. It is now more than 2 weeks later and I still do not have the shipment delivered. What has gone wrong? The parcel has been stuck in customs clearance since the 5th of August 2019, but it has been an absolute nightmare trying to obtain any feedback from FedEx via the call centre, where the waiting times were often excessive to being ignored by FedEx agents that have contacted me via email. I have also settled the clearance and VAT fees on the 8th of August immediately as requested by FedEx, yet a week later I have not received a single piece of feedback on when this shipment is actually going to be cleared and delivered.

It is truly disappointing to a point where I no longer want to order products from overseas and I would go out my way to avoid companies that make use of your courier services.
