If you mean that the meter was defective, you might try suing the manufacturer.
If you mean that it was installed wrong, you might try suing the electrician who installed it wrong.
If no lawyer will touch the case, then you should not sue in regular court, because it is hard to sue there without a lawyer. (Also, if the lawyers won't touch the case, that may mean that they think you will lose.)
You can sue in small claims court without a lawyer, but the amount that you can get is limited. For example, it might be just $5000.
