Horrible customer service!!! PRUDENCE!!!

I received a phone call from customs on monday for an international parcel im waiting for from tge company ibwork for, a company that uses fedex for all their parcels talking about over 100 000 parcels a year! I phoned fedex to track status as we dont send tracking numbers to the recipients. On the line it says press 0 if you dont have a tracking number, i first spoke to a lady that took my name and address and she tried looking for my parcel, i explained that my fiend received a call from customs and got a text after but i havent! He already received his shipment and i havent, the lady i called after was Prudence, does she have thee odassity to ask me how do i want her to find a parcel without a tracking number!!!! Ffs!!! The lady just before you was atleast trying, i told her the lady i was on the line with bedore you tied to search for my parcel and you rather just ask me how i want you to track it!!! Im having a call with management to change from courier services as soon as possible, as how will all our clients that spend thousands of dollard on our product feel with this service!!!! TOTALLY UNACCEPTABLE!!
