Bad service from the manager and employees

I went to the store last week Saturday 25 November 2017 to buy a plasma tv they told me i don't have a tv license i have buy it from them so i did buy it from them, and then after 30 min later they told me they have a system error i must wait, i left my documents there then went out to buy food i took long about an hour, i went back to lewis store but still they said they still have a system error then they said i must come back the following day morning (26 november 2017) they still have a system error i must wait, i did wait for hours then the system came right, the tv license was bought, one of the employees told i must sign after paying R1059 deposit i did sign, then they told me they have to interview me, when we were about to start, the employee told me the papers were wrong they have to change it. I waited for him till they close nobody attended me, Monday 27/11/2017 afternoon i went back to them i spoke to the manager he said i was late must come the following day, i did but still, then on 30th November 2017 i managed to go early before i go to work the interview was done the manager told me the first delivery will be at my place i had to pay someone to stay at my place for the day but they didn't deliver. Now this morning i called the manager i didn't even say a word he said he will call me back. BUT STILL HE NEVER CALLED AND I'M STILL WAITING
