krista has just one alarm system in her san francisco house. she wondered why was she getting two bills? >> one from city, one from bay alarm. >> first city sent this bill for 45ses today cover the registration fee. then another invoice came, this one from bay alarm, demanding $55 for what it called a city alarm permit. it seemed like two bills for the same thing. so she called bay alarm. >> i said well, i think i paid this before. they're like no. have you not paid for this. this is -- you have to pay. >> krista couldn't get answers from bay alarm or this city about the reason for two bills. so... she contacted 7 on your side. >> it's just sounding like there was confusion there at some point. >> that is the city treasurer. he says as far as he knows burglar alarms must be registered with the city and there is a fee. is its meant to hold owner as ktible for false alarms going off. now, owners can be fined. >> there is a number that has decreased. they're available to take care of real emergency autos krista shouldn't have to pay two fees. the
