If - regardless of reason - you’ve decided you’re not happy where you are and want to move on that’s your your prerogative. Your contract will tell you what you’re obligation is to the landlord over and above certainly paying for the time you lived in the premises. no one can reliably answer where you stand legally without being privy to the contract you agreed to. If you didn’t know what you were signing at the time that’s unfortunate- at least find out what it says now. Plenty of bilingual people around .
In my experience sometimes you rightfully get back your security deposit, sometimes you don’t. Sometimes you get a (lame) reason, sometimes you’re just ghosted until you give up. Not right or fair but Is what it is….
