at some point I lost my key to the house. I explained to the landlord that the key cannot be outside the house, since no one can enter or exit without a key.
I found the key a couple of days later and let him know.
After 3 weeks I moved out (after I returned his key) and he sent me a text that he will keep 100 pounds from my deposit, to replace the lock because I lost my key back then. I explained to him (I think for the 100th time) that the key was in the house all along and I’m expecting back my full deposit.
How can I make sure he will give back my money? Do I have a case here?
Thank you very much!
