FedEx has 24 hour response times via email

My package is at customs, and I understand that they are not the most efficient. However the support I'm getting from Fedex is equally as frustrating. I've been dealing with Unealia Adolph for 8 days now and she doesn't seem interested in assisting me. The turnaround time from her is 24 hours. It's as if Fedex has a dial up modem, and to save costs they dial up once a day to send and receive email. My shipper is a large American corporation, who supplies my company with corporate branded clothing. Fedex is but one of their freight companies and I will motion for them to be less favored than their other choices.
