switched from echostar 19 with gen5 service to echostar 17 against my will

I recently requested an installer to move my dish to the other side of my house. I was on echostar 19 duluth, mn and the service was great ever since I upgraded from Gen4 where i was on the horrible echostar 17. The installer who was only at my home at my request to relocate my satellite dish installed me on echostar 17 and my latency has been through the roof ever since. I did not request the transfer and I never would have asked for him to move my dish if I had know he was going to move me back to echostar 17. I have called several times and an installer has shown has cancelled twice. Today a third installer came and said he couldn't switch me back and in order for that to happen I would have to contact customer support again and ask for another installer to do it. I don't understand why they all can't do the same thing . When we called customer service we told them we needed to be put back where we were but the guy who showed up said he didn't know why he was here? He said I could call them for you but it would be better if you call them.? I don't see why he didn't call them and not leave until the situation was rectified.
