Notice of Entry being ignored, how can you get full deposit back?

By Erika

My landlord is selling his house, but I am currently living in his basement apartment. He has guaranteed us 24 h notice prior to entry by those looking at the house; however, there has been illegal entry into our apartment 4 times to our knowledge and possibly more.  My roommate and I feel like this is cause for our full deposit to be returned rather than just part which was specified in our contract. The problem is that notice is not expressly written in the contract it was just guaranteed via an email. Each time the up to the 4th time entry occurred we informed him that it was happening and asked it to stop. The fourth time it occurred he had requested the time the morning of which was less than 12 h to the time he requested and it was not an acceptable time. We told him no, but the apartment was entered against our permission. How can we legally get the entire deposit returned?
