Its been about 6 years! My credit report shows a bill from. Melrose on the bay apts. I refuse to pay what is unfair and I do not owe. Nobody returns my call to discuss this.

I lived at Melrose for 2 years. Signed a 3 month extension. (NEVER received a copy) Every month I'd go into office to pay rent. The last month i as always went in to drop rent in slot. I spoke with the woman who knew me and I said this is my last month. She said o.k. Lori...thats it. NOT that they had a certain form i needed to sign! When i left a few days early they said i owed a month because i didnt give notice and fill a form i knew nothing of. OF course i would have filled it out had i known. And as to notice a 3 month extension form and verbal said this is my last month makes 2 notices!
My credit report all these years still show i owe a months rent (for time i never was there a month past my 3 month extension) and its UNFAIR.
I called numerous times never got a return call from Element management.
