Fedex Couriers Bad Service and Unproffessional Stuff

I would like to complain that Fedex Cape Town is very unprofessional, staff needs to be trained on company processes n procedures.We were applying for a tender in Limpopo which closed on the 24/01/2020 at 11:00am n I went to courier the document on the 23/01/2020 at 08:29am for overnight delivery, the lady at the reception stated that the document will be delivered on the 24/01/2020 before 10:00am she even went to confirm with her manager Diseree or Martin, she even states that regarding tenders they take pride in delivery as early as possible n she stated i must call and track my parcel. Today i call at 09:30 n try to find out how far is my parcel(Tracking No: ***), the call centre agents tell me they will call me back after 10mins(i give them my number ***), which they dont n i call again n now the call centre agents tell me that the parcel is in Johannesburg n will only be delivered on Monday, I ask for sales managers contact details for Cape Town, the number given is not even answered*** n ***), Fedex needs to be held responsible for this we are losing business n money regarding their poor services n their not professional services, they need to be held responsible for this type of customer services. We are suppose to be informed as customers of services and procedures of Fedex, they need to take account for this and if nothing is done regarding this issue will take everything with my Legal team, if we dont receive an email regarding our loses before or on the 27/01/2020 i will be taking this matter further to our lawyers.
