Aarons Rent to own Buffalo New York

I  was in dire need of a new mattress in my home so I decided to shop around and I didn't have the money up front so I decided to go to Aaron's so I can put some money down and make payments. They tell me if you pay it off in 4 months it's the same as cash so that was my plan. I get to the store and the lady who helps me shows me a mattress in my price range but says to me 'let me ask my manager to see if I can get you a lower price' and of course this makes me excited and then she returns and tells me it will be lower. Well being lower was great and all but I didn't know a lower price meant a used mattress. I didn't know it was used until the guys showed up to deliver it and it was not in a package and I could tell it wasn't new. I needed a new mattress so bad and I don't like to complain so I didn't do anything about it at the time. Now a few months go by and the middle of the mattress gives out for no reason caused by me at all so I call and complain and tell them the only reason this could happen was because I was sold a used mattress. They told me they would have to take a look at it, so 2 guys showed up the next night after they told be afternoon but no one showed until the evening at 7pm, the guys take pictures and say the manager will contact me after he puts the picture into their insurance. Almost 5 days go by and still I haven't heard back from them so I decided to call, I'm then told I have to call them back in 2 days and then when I call back they finally say they will exchange my mattress. When they bring the exchange I notice it looks worse then the current mattress but there was no dent in it. I'm very unhappy with this company and the way they handle things and scam their customers.
