FedEx Failing on Feedback

I have lost so much money by choosing FedEx as a courier service. I cannot import anything through them without parcels being stopped by customs for "regulatory inspections". This is a common occurance and standard procedure, right? Ok well should it take 7 weeks from the date when I reported that I noticed the parcels have not have any movement?

This has been so costly that I have actually lost business because of a lack of follow ups or following common and standard procedures. All feedback I get are these generic email responses that are copied and pasted from a customer service handbook to try and prolong a response that they don't have yet.

No one can help on this.
