The other day some workers came to the house to shut off the electricity because we had forgotten to pay. Luckily we talked them out of it and took care of the $9 bill later that day. Since most people don’t have mail boxes and sometimes don’t even have house numbers here, the mail doesn’t work the same way it does in the US. So we don’t receive a reminder bill each month.
But basically the billing period for electricity ranges from 22-33 days. And if you forget to pay, you can always talk them into giving you some time. Actually, if I hadn’t let them through the gate they probably wouldn’t have been able to shut off my electricity anyway.
