how do you control a satelite? Mars rovers? Use Satelite internet that doesn't require a phone line?
Still don't see any proof from your side.
In the rare technologies which do allow communication with a Satellite you aren't bouncing your signal off of the satellite. You are sending a signal to the Satellite. The signal degrades massively as it proceeds up through the atmosphere. The satellite receives your faint signal, processes it, and broadcasts a reply in full power. The reply you receive isn't the same broadcasted signal you sent off to the satellite. That would be pointless.
Satellite Internet comprises of a series of one way signals between client and transceiver. At no point does the client bounce a signal off of the satellite or the satellite bounce a signal off of the client. The same goes for Satellite Phone and the other few ways to communicate with a satellite.
Sallite internet communicates with the sattelite up in space. Initially satellite internet used a phone line for the uplink. This was due to the fact that you needed licencing from the FCC/CRTC in NA and now that thats done with, two way satellite internet exists (In the US at least).
There are also plenty of other applications out there that use 2 way satellite, many of which involve big companies, worldwide telecomunications, etc.
However, the easiest way to verify would be to try it yourself. And you still don't have any proof that it doesn't happen. So you've failed once more.
