The right to terminate a lease when ”quiet enjoyment” is not possible.

The right to terminate a lease when ”quiet enjoyment” is not possible.
Hello,
I recently vacated my previous apartment after writing a letter to the leasing management corporation. I felt I needed to vacate because of numerous issues, but mainly that of squeaking floor boards from the apartment above mine, which prevented me from sleeping, making telephone calls, and basic concentration. The condition was extreme and management made no attempts to fix the problem. The decision to vacate was made on behalf of my health and sanity. I do not feel that I should have to pay for a termination fee (which is two times the monthly rent + security deposit), and I have told the company I will not be held responsible for such fees. I gave a thirty days notice, but they are implying that I will indeed have a financial obligation even if they find someone to rent the apartment next month. It is my understanding that the company has breached the rental agreement under at least one condition, that of breaking the covenant of quiet enjoyment. Am I correct in this assumption, and either way, am I legally obligated to pay any fees in this situation? Finally, if I am not obligated to pay any fees, and I am asked to do so, what should my next step be? Thank you so much!

Secuirty Deposit interest Los Angeles city
I’ve researched on the internet rules of returning security deposits to tenants, but found conflicting information. Some sites say tenants are entitled, some say landlords are required, some say different rates for different years, some say the same rate for every year, some say both security deposit AND last months rent collect interest, some sites say no, tenants are not entitled, some some tenants are only entitled if explicitly expressed in the rental agreement, etc. I live in the city of Los Angeles in an apt. bldg built before 1978, and I’d like to know if I can collect interest on my security deposit when I move out.

My landlord shut off my cable, phone, internet and washer & dryer breaker and then 2 days later there was notice to leave premises taped on my door. This notice gives me 30 days until it will go to court. My rental agreement stated that everything is included in the rent that I only pay the monthly rent. So everything is in landlord’s name. Can he turn off my stuff just like that. Does he consider those luxury utilities? Everything is to be included in the rent. If he cannot do this who do you go to to get them turned back on? The police?
