VERBALLY ABUSIVE AND INSULTING MALE COURIER TO A FEMALE CLIENT AND FEDEX CONDONES IT

On Wed 22/05/2019, I was expecting a delivery from TFG. Due to an emergency at home, I would not be available. I called TFG to advise and they said that its fine, my delivery would only be sent to me on Thursday 23/05/2019. I was fine with that and just incase made arrangements with a colleague to get my box. The delivery instructions on the box states - Please call me on my cell (***********) as Receptionist cannot sign for our parcels. On the 24/05 - no one called me but i got an email from reception stating that my order had arrived. I went to reception and a colleague advised me that the courier was there yesterday for me as well. I then informed her that I phoned TFG and of my delivery instructions - the courier then proceeded to tell me that I was lazy because I did my shopping online and that I should use my intelligence like he did - I would go to the store. I asked him for his Name and Surname but he said to me that he doesn't give his details to strangers. I told him that I would take it further. I then phoned TFG and spoke to Rehana because not only was this guy rude, my box was open and I took pictures of it. Today Rehana called me and read the email response, the courier freely admitted that he said so !!! but he said so because I HAD AN ATTITUDE PROBLEM!!!! Fedex official response was that I am lying, the box was not open. I have photos and witnesses to this. What kind of customer service is this. I logged onto the chat sight and no one responded except for a good day. I was verbally abused and insulted by a courier and then you have the nerve to say that I have an attitude problem. I am taking this further
