Hi guys
Went to a 2 bed 2 bath townhouse today.
Still one of those old beige prepaid meters with the red lever at bottom.

Owner says he is going through about 35 units A DAY with geyser, pool off.

It's absolutely chowing he's power.
Anyone seen this issue before?

Meter has not been tampered or fiddled with.

I turned mcb off the units stayed the same. Only plugs and lights on it chows again.
Could meter be faulty?
Out of "calibration"?

What can I do for or suggest to this guy?
Apply for a new meter?
