Renter (CA) in Need of Advice

I need a sanity check here. I 27f have been renting the same studio apartment since June 2021. I’m all and all a good tenant. IE: I am clean, quiet, and pay my rent on time. The only problems that I have ever faced was once asking my PM to change the locks on my apartment and once staying in the jacuzzi until 10:07 when the quiet hours start at 10.

I recently got a curt email from my PM accusing me of some pretty severe noise violations. All of them were untrue, with several of the documented dates being times that I was not even at the premise due to me either housesitting for my parents or staying with them due to doctors appointments being in their area. I replied to my PM with this with no response.

As a side note, I have a seemingly mentally ill neighbor with a poorly trained dog, who has threatened me for staying in the jacuzzi until 10:07, tried to record me, and implied that she owns a firearm and will “do what is necessary to protect herself and her dog because she isn’t like us from California.” I’ve also had the lock on my mailbox broken twice since last June. Additionally, with my lease agreement, I am paying over $200 per month less than what a new tenant would pay for my place.

I will most likely move out in the summer and all of the short term leases are out of my budget. Living with my parents is not a possibility.

How concerned should I be given the false report, adversarial neighbor, and mailbox issue? How can I fix this? Because most of my previous housing has been out of the country or informally staying with friends, I need this place for my rental history.
