California Renter Question

[Jeffrey Lobel]

Hi, I was currently offered a notice of change of terms to my lease agreement since my initial lease is about to expire in a few months. I noticed that the price on the change notice was clearly listed. When I inquired they said that it went up a $100 even though the form clearly states the price that they were offering. I was curious what legal grounds I have to their offer since their notice clearly states the price they are asking for.
