<prompt> Human: I work in a pretty dense area downtown, and pay 160 per month for a parking contract which started in January. I paid the initial bill to start parking, but when I received my bill for February it was 0 and marked Complimentary. I called to inquire because this didnt seem right and they claimed it was an error, a few days later I checked my account and a manual charge for the correct amount was added to my account and I paid.Now for March the same thing has happened. It seems they havent updated their system and use a work-around last time this happened. My question is what do I do? I have the money to pay the bill but I dont feel obligated if they cant get their shit together. I have proof that the bills are for the correct parking ramp, and they say right on them complimentary. Am I legally obligated to pay if they finally realize whats happening?  <response>: Id keep the money handy in case they ever do get their shit together. They are issuing you bills that say complimentary. Its their fault. Dont pay until they ask you to.
