It's not really clear what is happening.
Do you pay rent by the month?
What day of the month is the rent due date?
What's the 30 days all about?
Are you moving out at the end of 30 days?
Did you give written notice?
Did the LL give you written notice?
On a month to month tenancy the statute only requires 15 days notice to the end of a rental period.
