Rude and arrogant Technician

I've had the worst customer service experience ever,I called SAMSUNG Mall of Africa on Sunday to ask for a quotation for my Samsung J8 LCD that is broken,I first spoke to a gentleman by the Lionel who then transferred me to a technician,a gentleman by the name Washington Tshuma who left an after taste in my mouth to this day,when I asked him for a quotation he said to me he cant give me a quote because of I am call center agent mind you I dont even work as a call center agent,then he said to me he will call me back and I tried to explain to him that our office number is link to our office in Fourways and Capetown so if he is going to call me exactly on which number is he going to call me on,he then reffered to me again as a call center agent,a colleague of mine decided to call the same number on her phone coz she heard what was happening at that after 15 minutes or so of not getting anywhere with him I asked to speak to the manager who was Lionel. I asked for a quote he gave me the and explained to me that I must go to the shop at Mall of Africa to pay a deposit and they will order the part.On that same day after I had knocked off I drove there,when I was expecting an apology from Mr Tshuma for not helping me over the and for insisting that I was a call center agent,I was never ready for the arrogance that I got from no apology what so ever instead he said hes been in the industry for a very long time and he know that everybody that calls is from the call center and they are not allowed to give quotes to call center agent even when I was in front of him he still said that to me. At that point I saw I was getting nowhere with I asked to pay and the part and I asked how long it will take for part to get there and how long it would take to fix it. He said to me he will order the part Monday morning and the part might delivered in the morning but if not it will definitely be delivered late in the afternoon around 16H00,then he said to me if the part gets delivered in the morning he will give me a call,and he said it will take him 45minutes for him to fix it,I decided to pay the full price and I did not leave my phone I told him if he doesn't call me in the morning I'll call in the afternoon before I leave work. I called after work and I asked to speak to him again,I said I take it that the part did not make it in the morning,I would like to find out when it would be delivered so that I can bring my phone,as if the bad attitude and arrogant behavior that I got from him on Sunday wasn't enough he gave another 1 on Monday,told me he does not work with deliveries and how will know when my part will be there to my disbelief,I asked to speak to Lionel again told him happened,he told that it wasn't there and they will give me a call the following day and that didn't happen again I call yesterday again I spoke to the other manager who told me it takes 3 to 4days for the part to be delivered that's all I was asking for as a customer honest and accurate information but what got from Washington was a rude and arrogant behavior. To this day my phone is still not fixed
