Contrary to C-Pills expected INCORRECT 'response'....
If your rent was paid in full for the full term of the lease, the landlord has NO legal right to remove any of your property or to remove the premises from your control before the end of the stated lease period.
Under California Civil Code, as follows, and since the OP says "the rent was paid untill the end of the month", clearly, the landlord was at fault for an IMPROPER assumption of abandonment.
1951.3.
(b) The lessor may give a notice of belief of abandonment to the lessee pursuant to this section only where the rent on the property has been due and unpaid for at least 14 consecutive days and the lessor reasonably believes that the lessee has abandoned the property. The date of termination of the lease shall be specified in the lessor's notice and shall be not less than 15 days after the notice is served personally or, if mailed, not less than 18 days after the notice is deposited in the mail.
(e) The real property shall not be deemed to be abandoned pursuant to this section if the lessee proves any of the following:
(1) At the time the notice of belief of abandonment was given, the rent was not due and unpaid for 14 consecutive days.
(2) At the time the notice of belief of abandonment was given, it was not reasonable for the lessor to believe that the lessee had abandoned the real property. The fact that the lessor knew that the lessee left personal property on the real property does not, of itself, justify a finding that the lessor did not reasonably believe that the lessee had abandoned the real property.
(3) Prior to the date specified in the lessor's notice, the lessee gave written notice to the lessor stating his intent not to abandon the real property and stating an address at which he may be served by certified mail in any action for unlawful detainer of the real property.
(4) During the period commencing 14 days before the time the notice of belief of abandonment was given and ending on the date the lease would have terminated pursuant to the notice, the lessee paid to the lessor all or a portion of the rent due and unpaid on the real property.
Send (certified RRR) the landlord a written accounting of all the damaged, missing property with proof of CURRENT market value (not retail) and ask that they reimburse you for the loss. Give them a reasonable time to respond (5 days from receipt??). If the don't respond and if the amount of damages is less than $7500, sue them in the local small claims court.
