^^ there is a solution if want to do it. But need to fight hard.
We all have digital cameras in our phones or separatley. We can take picture of meter after every 5 days with date mentioned on picture.
This will be proof with us that we noted meter reading with time stamp.
Now this process need to go for 3-4 months so we have good record.
Then we need to go for courts and sue them for our life time bills or over bills.
I know courts are tough part, but we as group need to do it. I am sure if we 10-20 people do this, taking pictures and then gathering them up, will give us result after 1-2 years and hopefully in future they will get lesson.
I will check my meter for next 2-3 months.
