Southwest Security Storage

I've had so many trouble with these people here. When I first got my storage they said they would sweep it before I put my stuff there then I go and I has tons of dirt. Second, I paid 3 months in advanced and it said it was paid to specific date then they wouldn't let me in saying I owed money. After I cancelled and got my things out I got a letter months lates saying I owed like 500 dollars for previous months.
