Cairo electricity bills

Hi,
What happened if you fail to pay electricity, gas etc bills? Living in el rehab.
Do they cut off supply immediately?
Or how many months owing before they cut off supply?
When is electricity bill collected in the month? Beginning of the month or end of the month?

Does anyone know if electricity bills in el rehab is still read by a meter reader person?

A fair guess is that supply will be cutoff.

Yes. I'd assume so. But how many months owing before they cut supply.
I read somewhere that if you owe more than 3months, they cut it off.
Or do they do it immediately after the first month?

I would think cut off would be after one month.
