Inefficient unreliable service

On 24th I called for installation of extra view with new decoder as an error message E 143. The problem was cited as poor installation as the picture came and go. I called 4 to 5times with airtime of R30 each time. I took both decoders to multichoice at N1 city in cape Town and diplexer was cited as problem and they don't keep it in store hence I have to get it on Monday 27th June 2018. I found it at brights in Bellville for R90. The set played for an hour on Saturday and cut off citing E143. I called multichoice again 2 times with agents doing their best to help to no avail. I laid complaints to. Multichoice and they responded on 25th to send their installer on 27th. I am now at home waiting and the installer called me citing they are in Soweto and I am in Western cape as they were sent to wrong address. Multichoice called at 11h40 to send installer. Have not enjoyed the service since 20th of June and my installment is due on 1st July with a week of not watching what has been promised by multichoice and game.
