Tempoe Why Not Lease it They put me in a f****** 18 month lease contract that I was not told about until 4 months down the line. Internet

 I was supposedly financing 4 speakers and a radio and what I was told at Mickey Shorr is that once I pay the system off I would own it. Well 4 months down the line I miss a payment and they add a late fee so I call to get the late fee waived and they tell me they'll waive it. Well a little more talking with them and they tell me I am in a 18 month lease for 95$ a month. Now this totally surprised me because of what they told me at the store and the Tempoe agent even said that they have had people complaining about the same thing and there is nothing they can do about it. They proceed to tell me that I would have to pay 95$ two more times and then buy out the lease for 290$. Now I have already made 4 payments of 95$ and the equipment is only 500$. So basically I'm paying 7-800 dollars for 500$ equipment. this company is a total scam and they are now taking money from my bank account whenever I put an amount in. I know this can't be legal especially with the circumstances. All I need to know is do I have enough information to sue them because I will not be paying them anymore and I most likely will have to switch my bank. Please help or chime in if the same thing happened to you.
