Electrical, worries

[87651]

We have popping, noises like boxes turning themselves on when not in use & most recently loud electical pops, a banging or drumming like noise when switching channels. Service has been here a number of times, last issue, phone calls dropping off or ringing, to pick to busy signal, that was fixed, seems the new power back up didn't mesh with software on other electrical features, All these plugs & the increase in electric usage with Verizon, makes me uncomfortable. If TVs & boxes are switched off why are they making noises & using electricity? Beginning to think I'm being watched by Big Brother via, all this electrical crap Verizon has installed in our house
