Yes. In my previous place in India the RCD was repeatedly tripping up. Earth here was a metal rod into the ground, and I only found out much later they fixed the RCD issue by disconnecting the rod and I started getting electric shocks from touching my fridge while my crappy toaster was connected. That's when I decided to not mess with electrics in India. It's dangerous enough as it is. As for the 70V, I eventually managed to reach someone in the electrics company that understood my issue, and they told me a local transformer for the whole street was broken. And they didn't have any plan to fix it.
