Poor customer services at game Springsmall

Hi as customer I went to game springsmall in July to lay bye hisense 40 inch TV which was on promotion and I was given 3 months to pay it off which I did. 1 week ago I received a call from game sales lady telling me that my laybye will soon be expired so I heard I decided to go and finish paying my laybye which was today I was on my lunch time I got at game at around about 13:10 then I stood by the queue. After paying they requested for my TV licence which I then gave it to them. Then they called one of the assistant who wasn't interested in helping and he/she came there and requested my ID then you got a copy of my ID with you then he screamed again for my ID then I told him my ID copy is there with you. Then system was offline for TV license then I asked then can I give them my proof of payment for TV licenses so that I can go cause I'm getting late then they called tshepo to come and assist then asked then if they could kindly deliver the TV to where I work which is 10 minutes away from the mall I will leave everything with them since it's not my fault for the system to be offline then they denied to assist until I was 10 minutes late and then I ask them what is the solution then they all answered I must come back then I told I'm using diesel to drive up and down which will end up costing me the same as the original price of the TV when it's not on special. Then asked for refund cause no 1 wanted to assist me and I'm really ****ed, upsets that I couldn't get the TV I wanted with all my heart just because of poor customer services. Can you please assist what do I do now
