useless agents

I am a very unhappy customer right now. I have 2 decoders, 1 decoder is working and my new model 5S decoder is giving me problems to connect as my extra view decoder. this issue has been going on since Saturday (06 July 2019) until today I have not been able to watch from my extra view. I am very disappointed with the agents I have been dealing with to fix the E143 error I see on my secondary decoder. the agents are either not knowledgeable, don' t care or impatient.
