Significant Power/Voltage Even After Turning off Main Switch

I turned off the breaker to a light switch to work on the light switch but I was still registering a voltage on my tester and was getting shocks when I touch the wire.
I decided to turn off the main breaker to the entire house and nothing changed. My tester was still glowing and I was still receiving shocks.

What could be causing this?

Your main breaker is likely faulty and stuck 'on'.

It doesn't seem to be the full voltage because the lights go off but there is enough voltage to make the tester glow and give painful shocks
