Extra view television not working

All along I have 2 TV,a in my home. The main is in my outside flat and the secondary one is in the main house. Yesterday my niece who lives above my flat baught her nown new TV, which means that we now have 3 television sets in my home/yard. 1 main one and 2 extra views. ( MY NIECE HAD A TV BEFORE BUT WHEN IT STARTED GIVING HER PROBLEMS SHE GAVE IT AWAY. THIS MFEANS THAT THERE WAS A TIME WHEN WE HAD 3 TELEVISIONS. After she had given away her old one she stayed for a very long time without a TV hence even my monthly subscription is R514.00 per. ( 1 main and 1 extra view). Yesterday after her new TV arrived she connected it. I then called Multichoice and spoke to more than 6 agents asking them to connect hers so that I can now pay for my primary one and the 2 extra views. They did that however 1 extra couldn't function. I called about 6 different agents who tried to assist me with the connections but nothing worked I still said to them that I am aware that at the end of this month my installment will increase with the new extra view added and still said to 4hem I know that the pre.ium for the new one will be prorated because it's was installed in the middle of the month. The error is still not fixed her new one and my main one are working but the one in the main house is not. The error message says E143-0. I am unable to call them my airtime is finished. If this is not fixed today I cannot pay for 3 television sets is only 2 are working. PLEASE HELP.
