Driver Harrasing and insulting me

I've never been so angry and harrassed. Today I received a call from your driver telling me his here to deliver my furniture bought. I then went to attend them upon arrival the driver tells me it's not his job to load the furniture off the truck or whatever they use to deliver with. So I then asked him who must do it he tell me I must do it myself. He then further told me his not allowed to even lift furniture upstairs as it's not company policy I then asked so who must do it he said i must pay him extra to do it mind you the delivery was on the 27th February 2020 at 19:05. I then asked why do they even deliver so late he said to me he doesn't control the weather it was raining I proceeded to tell him that is he aware that I asked for delivery to be on the 28th of February 2020 he said there is no delivery date in his invoice so whilst talking to him they kept laughing at me and speaking to me in a language I didn't understand which I think is Tsonga. I said to him please speak to me in a language I I understanding then they still all 3 laughed at me now mind you I'm with my 5 month old son I the rain. I told them since they can't do what is required of them they must return with their furniture I just will want my money back they still had the nerve to call me when they left to swear at me. Dear Fair price can I just get my money back Thank you
