Sample Sign The Agreement Please Help Me Draft A Letter - I Did Not Sign A Lease But Vacated The Apartment?

Please help me draft a letter - I did not sign a lease but vacated the apartment? - sample sign the agreement

Hello,
In January, I paid the rent and do not sign a security deposit for an apartment, but the contract. I changed my clothes, he is now empty. (There are many reasons (long story) I've decided to live there.)

I still have the keys to the apartment, and I want to give the keys. How to write a letter, what to say and how shall I say? Since there are only a few days, I ask for some rent and security deposit?

PS Here is an excerpt from the letter that I found on the web, but only for people who are already on a contract to help - please send me formulate this .... have signed, I would appreciate it!

PS In brief, I am writing this letter to the fact that I never had a lease, but pays only play for the tenants of the first months and security deposit. I would also like to say that I have the keys - I am also in the letter also?
