I am not going to be an accesory to grand theft voltage, but what they do is remove the meter and put plastic sleeves over the contacts so they will be insolated from making contact. They put the meter back in and no juice for you! It is quite dangerous for someone without knowledge to do.
I went to a service call where some of the house was dead (including half the dryer, lights but no heat) after a little searching, panel service drop etc, I removed the meter and found the plastic sleeves. Turns out they had just moved in and the power was supposed to be turned back on. When the guy came they told him that it is on already and they were all set. He never removed the meter or the sleeves. One plastic sleeve was worn through and allowed the jaws to make contact thereby powering most of the house. When they found some things not working they called me.
