Atrocious service, no sense of urgency and a whole lot of unfulfilled promises

It's actually exhausting that we always have to complain to get service from FedEx. Our parcel has been on "clearance delay" status for a week now and I called 4 times already, I always get told "We have escalated it and we will move it forward for clearance asap". We paid for express courier for a reason, our business is on stand still and customers are waiting on us. We are already dealing with losses due to a pandemic and now their incompetence has made things worse for us as a startup business. This is unacceptable and it's actually disgusting from International courier company who prides themselves in offering exceptional service.
