Robo call re phony rate rebates or increases on utilities. Do not do business with these low life -- the calls in violation of the FTC rules show their lack of respect for the law, the phony number shows their attempt to evade it. Do not press number to be removed, it will just give them your number so they can give it to other lowlife.
