Federal Express Fed Exp; Fed Ex, FedEx Guaranteed Delivery, Failed, No Refund, No Consideration Memphis TN

Our Company has used FedExp for years and had the occasional concern and were appropriately assisted.  I don't know what happened, but the Compay paid extra to have a guaranteed delivery, confirmed by the Fed Express Agent in Orlando to have an important package delivered by Thursday Feb 25 to Puerto Rico, sent on Tues Feb 23.  For a small box weighing about 4 pounds, the Company paid almost $50.  We confirmed today, Feb 26 2021 that the package was delivered to TN.  I'm not sure why it is in TN, but it was supposed to be delivered to Puerto Rico. 

They could not give me a specific delivery date.  Given that on Feb 27 we had arranged for workers requiring this shipment that will now cost us about $350, the least Fed Exp could do would be to provide an apology and refund the money.  It would have been better to send it USPS and for a fraction of the cost.  The live agent said they no longer provide consideration for screw ups or failed promises or over changes and that she would not escalate this to a supervisor nor provide me with an email or contact point to escalate this complaint.  Not good business policies FedEx.  From here forward we will be using alternative carriers that care.  Be ware of bogus claims of timeliness by FedEx and horrible customer service and experience.
