Southern Management Systems Inc. Debt Collection Complaint

Southern Management Systems Inc. Debt collection department,

Cont'd attempts collect debt not owed Debt is not mine Florida

I signed a lease with an apartment complex without having a guarantor ( need - according to the contract ) and the day after, I had to cancel it because my roommate was no longer able to move up as a result of a background check. I tried to cancel the lease in writing the following day and they told me I was stuck in it. I told them I would not be living there and to rent it out to someone else. They in turn rented it out. Over a year later, they contacted me telling me I owed over $8000.00 for the lease. Upon receiving this bill, I called, told them the problem, and now they are trying to charge me $350.00 for a cancellation fee. They rented out the room without telling me anything about it and were originally trying to charge me the full amount until I called. This is criminal. I did not live there and cancelled within 24 hours.
